Hi, cupcake. Best wishes on your journey of discovery.
I don't think the bible specifies any "true religion". The Jewish people were especially called out from among the nations (Deuteronomy 7:6) and the Jehovah's Witnesses claim that they are the inheritors of this special blessing, but the bible account shows that Jesus' sacrifice changed all that (John 1:7). The hope of salvation is now open to all people.
If we want to try and compare all the Christian denominations, for instance, and figure out who most closely follows the bible, that would be a different exercise. The Jehovah's Witnesses closely follow some bible commands, and ignore others.
Here's some other scriptures to ponder:
1 John 3:1 - We are the children of God.
Psalm 19 - Creation speaks to the whole world (ver. 4) of the glory of God.
Acts 17:22-28 - Even the pagans recognize the one God, our creator, and he is not far from any of us.
