I am the way and the truth and the life. No one comes to the Father except through me. If you really know me, you will know my Father as well.
Despite what our current Politically Correct culture would have you believe, you cannot be a Christian and believe that other religions offer valid ways to God in Heaven. Jesus stated very clearly that He was the Son of God and that acceptance of His salvation was the one path to God, His Father.
In simplest terms, either He was a liar or that statement is true. If you see this statement as a lie or wrong, He is not your Lord and savior. If his words are true then other religions have no validity and that those that follow them are doomed to pay for their sins.
That does not mean we should treat non-Christians badly. In fact, Jesus himself tells us to love them. How else can we show them the path to redemption? How else can we share the Gospel and the good news that Jesus Christ paid for those sins if they will just accept the offer of salvation?
Is that easy? Nope
Are any of us 100% successful at it? Of course not, by our very nature we are fallible otherwise we wouldn’t need His Grace…
