“For this is  good and acceptable in the sight of God our Savior, who desires all men to be saved and to come to the knowledge of the truth. For there  is one God and one Mediator between God and men, the Man Christ Jesus, who gave Himself a ransom for all, to be testified in due time,”. ( 1  Timothy 2:3‭-‬6 NKJV).

Jesus said to him, “I am the way, the truth, and the life. No one comes to the Father except through Me”. (John 14:6 NKJV).

“Jesus said to her, “I am the resurrection and the life. He who believes in Me, though he may die, he shall live.  And whoever lives and believes in Me shall never die. Do you believe this?”(John 11:25‭-‬26 NKJV).

THEORY TRUTH  IS:

“And as Moses lifted up the serpent in the wilderness, even so must the Son of Man be lifted up,  that whoever believes in Him should not perish but  have eternal life.  For God so loved the world that He gave His only begotten Son, that whoever believes in Him should not perish but have everlasting life.  For God did not send His Son into the world to condemn the world, but that the world through Him might be saved. “He who believes in Him is not condemned; but he who does not believe is condemned already, because he has not believed in the name of the only begotten Son of God.  And this is the condemnation, that the light has come into the world, and men loved darkness rather than light, because their deeds were evil.  For everyone practicing evil hates the light and does not come to the light, lest his deeds should be exposed.  But he who does the truth comes to the light, that his deeds may be clearly seen, that they have been done in God.” He who believes in the Son has everlasting life; and he who does not believe the Son shall not see life, but the wrath of God abides on him.”(John 3:14‭-‬21‭, ‬36 NKJV).

“..that if you confess with your mouth the Lord Jesus and believe in your heart that God has raised Him from the dead, you will be saved. For with the heart one believes unto righteousness, and with the mouth confession is made unto salvation. For the Scripture says, “Whoever believes on Him will not be put to shame.” For there is no distinction between Jew and Greek, for the same Lord over all is rich to all who call upon Him. For “whoever calls on the name of the Lord shall be saved.” How then shall they call on Him in whom they have not believed? And how shall they believe in Him of whom they have not heard? And how shall they hear without a preacher? And how shall they preach unless they are sent? As it is written: “How beautiful are the feet of those who preach the gospel of peace, Who bring glad tidings of good things!” But they have not all obeyed the gospel. For Isaiah says, “ Lord , who has believed our report?” So then faith comes by hearing, and hearing by the word of God”. (Romans 10:9‭-‬17 NKJV).
