Jesus told him, “I am the way, the truth, and the life. No one can come to the Father except through me. John 14:6
Jesus is the ultimate sacrifice for your sins, the name above all names, he who was given all authority, the redeemer. It is only through Jesus that you are saved and can enter the kingdom of heaven. Believe it, receive it and openly declare with your mouth and actions (baptism, reading the Bible daily)
If you openly declare that Jesus is Lord and believe in your heart that God raised him from the dead, you will be saved.
Romans 10:9
Simply put, if Jesus is not the only way to God, then He is not any way to God. If there are many roads to God, then Jesus is not one of them, because He absolutely claimed there was only one road to God, and He Himself was that road. If Jesus is not the only way to God, then He was not a honest man; He was most certainly not a true prophet. He then would either be a madman or a lying devil. There is no middle ground available.
“Beware of false prophets, who come to you in sheep’s clothing but inwardly are ravenous wolves. You will recognize them by their fruits. Are grapes gathered from thornbushes, or figs from thistles? So, every healthy tree bears good fruit, but the diseased tree bears bad fruit.
Matthew 7:15â€-‬17
A healthy tree cannot bear bad fruit, nor can a diseased tree bear good fruit. Every tree that does not bear good fruit is cut down and thrown into the fire.
Matthew 7:18â€-‬19
