Proverbs 14:12 (NKJV)
There is a way that seems right to a man, But its end is the way of death.
There are a lot of different religions in the world today. Can they all be right? Of course not; truth by definition is exclusive. Why do these cults and other "isms" continue to grow? Religion is all about man and what he has invented for himself. Christianity is not a religion; it is a relationship. No other religion has a savior. In no other religion does God provide a way for a man to be saved without any merit (good works) on his part.
Don't fall for the "feel good" "I'm OK, you're OK" trap. All ways do not lead to God, even the ones that "seem right." There is only one way that leads to eternal life and all others lead to eternal death.
John 14:6 (NKJV)
Jesus said to him, "I am the way, the truth, and the life. No one comes to the Father except through Me.
Romans 5:8 (NKJV)
But God demonstrates His own love toward us, in that while we were still sinners, Christ died for us.
