How would someone know any better if they were raised in a different religion?
**All scripture is from the New International Version unless noted otherwise.
The Bible tells us in Ecclesiastes 3:11 that God has set eternity in our hearts. He has given us knowledge of Him even in His creations (Romans 1:20.) Which means that God has put the knowledge of His EXISTENCE into our hearts. The reasons we do not pursue Him and grow in knowledge of Him is because of our own pride and selfishness . In Deuteronomy 4:29 we learn that God is available to us when we call!
Should we decide to seek Him, who has been instilled in our hearts, we will find Him. It’s as simple as that. God is a Just God. When people blatantly deny Him, their hearts are cold and they will not see eternity in Heaven.
