How Do I Parent Adult Children Who Have Walked Away From the Faith?

Question 11151.

Prodigal adult children break a parent’s heart in a way that is genuinely hard to describe to anyone who has not lived it, and I have sat with enough grieving parents in my study to know that generic reassurance rarely helps. What helps, I think, is Scripture’s own most famous story about exactly this situation, and a clear sense of what a parent can and cannot do once a child has grown and chosen a different path.

Luke 15 gives us the parable of the prodigal son, a passage that speaks into the same terrain as parenting teenagers in the faith but from the far harder vantage point of years of apparent silence, and I want to draw from it directly here, because it is not simply a story about a wayward son. It is also a story about a father, and his posture toward that son, tells parents of prodigal adult children almost everything Scripture wants us to know about how to wait.

I write this as someone who has walked alongside more than one family in exactly this grief, and I would rather give you the substance of Luke 15 slowly and carefully than rush past it for a quicker list of tips that will not hold up on the hardest nights.

What the Father in Luke 15 Actually Does

The father in Luke 15 does not chase his son into the far country, does not send messengers to drag him home, and does not disown him in anger before he leaves. He lets him go, painful as that must have been, while apparently watching for him daily, since Luke 15:20 tells us that while the son was still a long way off, his father saw him and felt compassion, and ran to him. That single detail, still a long way off, suggests a father who had been watching the road for a long time, hoping, without controlling or coercing a return that had to come from the son’s own will.

I find it striking that the father runs, which in that culture was considered undignified for a man of his standing, hiking up his robes to sprint down the road toward a son who had squandered half the family estate. Whatever restraint that father showed while his son was away, none of it was coldness. It was a controlled, painful patience that broke into unrestrained joy the moment welcome became possible.

The Limits of a Parent’s Responsibility

You cannot believe for your adult child, and you cannot repent on their behalf. Ezekiel 18:20 makes plain that each soul is accountable for its own sin, not for a parent’s sin nor a parent for a child’s. This is not a comfortable truth, because it means there is a real limit to what even the most faithful, praying parent can accomplish, but it is also a mercy, because it means your child’s choices are not solely the verdict on your parenting. Prodigal adult children make their own choices as genuinely responsible moral agents before God, just as the prodigal son did.

Staying Connected Without Approving Everything

The father in the parable does not require the son to clean up his life before receiving welcome, but the narrative also does not suggest the father funded further prodigal living or pretended the son’s choices had been wise. There is a difference between keeping a relationship open, answering calls, sharing meals, expressing love, and actively enabling behaviour you believe is harmful. Most parents of prodigal adult children I have counselled find real wisdom in staying warmly connected while being honest, when asked, about their concerns, rather than either cutting contact entirely or silently funding a lifestyle they believe is destroying their child.

Drawing that line in practice is rarely tidy. I would encourage parents of prodigal adult children to distinguish between ordinary relational warmth, which should rarely be withheld, and material support that directly enables continued harm, which wisdom often counsels against. A meal together is not the same thing as a cheque that pays for what is destroying your child, and most parents already sense the difference even when it is hard to hold the line.

Praying Without Ceasing, Literally

1 Thessalonians 5:17 says pray without ceasing, and I have watched parents of prodigal adult children turn that verse into an actual daily discipline, praying by name, by specific need, sometimes for years without any visible change. Augustine’s mother Monica prayed for her wayward son for decades before his conversion, and the church still tells that story because prayer sustained across a long, apparently fruitless season is exactly the kind of faithfulness Scripture commends, even when we cannot see what God is doing.

Guarding Your Own Heart From Despair

Grief over a prodigal adult child is real grief, and I would encourage you not to minimise it or feel guilty for how heavy it sits on you. Psalm 34:18 promises that the Lord is near to the brokenhearted, and that promise is not a platitude, it is meant to be leaned on specifically in seasons exactly like this one. Find another believer who will pray with you regularly, because carrying this kind of grief in isolation, much as I have counselled about the danger of unresolved guilt and unforgiveness more generally tends to curdle into either despair or a controlling anxiety that pushes an adult child further away rather than drawing them home.

I would also gently say that other people’s advice, however well meant, can sometimes wound more than help. Comparisons to another family’s prodigal who returned quickly, or unsolicited theories about where you went wrong as a parent, rarely serve a grieving parent well. Choose carefully who you let speak into this particular grief, and give yourself permission to set that boundary without guilt.

Leaving the Timing of Prodigal Adult Children to God

The parable does not tell us how long the younger son was gone, only that his father was watching when he finally returned. Some prodigal adult children come home in months, others in decades, and some, tragically, do not return in this life at all despite years of faithful prayer. That uncertainty is genuinely hard to sit with, but it does not change what faithfulness looks like in the meantime: watching the road, keeping the door open, and trusting the outcome to a God who loves your child even more than you do.

The Older Brother’s Warning

Luke 15 does not end with the younger son’s return. It ends with the older brother refusing to join the celebration, resentful that grace was extended so freely to a sibling who, in his view, had not earned it. I think this half of the parable is worth applying to parents of prodigal adult children too, particularly if there are other siblings who did not wander and may feel, understandably, that a returning brother or sister receives disproportionate attention and relief. Watch for resentment building in the rest of the family even as you rightly celebrate a prodigal’s return, and make space to honour the quieter faithfulness of children who never left as well.

When the Prodigal Does Not Return

I would be dishonest if I did not address the hardest version of this question directly. Some parents of prodigal adult children carry this grief to their own graves without ever seeing the return they prayed for across decades. Scripture does not promise every prayer for a wandering child will be answered visibly within this life, and I will not pretend otherwise for the sake of a tidier ending. What Scripture does promise is that your prayers were not wasted, that God sees every tear, per Psalm 56:8, and that your faithfulness in loving a prodigal well, without controlling or abandoning them, was itself an act of worship regardless of the outcome you were able to witness.

So, now what?

If you are watching the road for a prodigal adult child right now, you are in good biblical company, standing where the father in Luke 15 stood for however long it took. Keep loving without controlling, keep praying without giving up, and keep the door open without pretending harmful choices are wise ones. That is not passivity. It is exactly the kind of costly, patient love the father in the parable modelled for us.

Whatever the outcome, and however long the waiting, your faithfulness in this season is not wasted, even on the days it feels invisible.

I think often of the many parents of prodigal adult children in my own congregation who have taught me more about patient, hopeful love than any commentary ever has. Some have welcomed a son or daughter home after years of silence. Others are still watching the road tonight. Both groups have shown me what it looks like to trust God with a grief too heavy to carry alone, and I count it a privilege to walk that road alongside them.

But while he was still a long way off, his father saw him and felt compassion, and ran and embraced him and kissed him.
