I have perhaps a silly question, but one that is tugging at me nonetheless…Who will go in the Rapture? Is there an age in the Christian faith at which we are to be held responsible for our own faith?
No, yours is not a silly question. There is disagreement in the Church as to who among us will qualify. I believe all born again believers, children below the age of reason (including the pre-born), and those who are not mentally capable of understanding the consequences of sin will go in the rapture. I believe the Bible says that our inheritance was guaranteed at the moment we first believed (Ephes. 1:13-14) and that God took ownership of us at that moment and accepted responsibility for us (2 Cor. 1:21-22). I also believe all children belong to God and have eternal life (Romans 7:9) and that He’ll treat the mentally handicapped as if they are children. He doesn’t condemn anyone for not understanding something they’re incapable of understanding.
There is no specific age mentioned in the New Testament at which we’re held responsible for our faith. It’s more a matter of intellectual development than physical maturity.
