Welcome to the forum,
It’s not unusual to rethink what you believe as you go through the teenage years. All my children came to church with me, but In their teenage years they started to think for themselves rather than believe just because ‘ mum did ‘. That is part of the journey as you evaluate your own thoughts on the whole matter.
My youngest was pretty much where you were up until last year ( he is now 28 )
He had a respect for Jesus and the New Testament and would listen to Jordon Peterson discuss the Bible. He would have classed himself an atheist. Gradually over many years, and after he decided to re read scripture, he found that He believed it and came to faith last year.
The Lord used many things, including an accident to get his attention but Jordon Peterson ( who was not a believer as such ) played a big part. Also I never preached to him, just discussed things when he had questions………..
My other three children have mixed views, my oldest is a skeptic, my middle son is t sure , my daughter was a believer but the church didn’t really act in the right way towards her and she drew back. She still has her Bible but it’s difficult to know exactly where she is, she is still open and my youngest often discusses things with her. Me, I pray for them but know they have Togo on their own journeys as it has to be real and not just to fall in line with me xx
