Over the years I've noticed how impressed Christians are by the testimony of those coming to Christ from lives of crime, drink, drugs and immorality. Yet when hearing the testimony of someone coming to faith in Christ from a Christian home when they were a child, they don't seem as impressed. It's forgetting that the salvation of anyone is a miracle of God's grace. It isn't the case that the salvation of a child from a Christian home is easier than that of others.
Sometimes because of this, children converted in Christian homes can doubt their conversion and think it would have been better to be converted from some awful background. They should realise many converted later in their lives wish they had found Christ earlier and as a result avoided certain sins, wasting many years.
The child in a Christian home hearing God's word can see their sinfulness. The Holy Spirit can convict them of their sins and need of Christ. Really those coming to faith in Christ as a child in a Christian home should be so thankful for that. The sadness will be if you have done so little with the blessing of being converted as a child.
You may be reading this having been brought up in a Christian home, but you still haven't believed on Christ. Jesus warned it would be more tolerable on the day of judgement for Sodom and Gomorrah than it would be for Capernaum (Matt. 11v22,23) who had the blessing of Christ's ministry amongst them. You see the worst of the ungodly who never hear of Christ will fare better on the day of judgement, than those from Christian homes with so many spiritual privileges and yet continue rejecting Christ.
