Only Belief in Jesus Christ can Save
Jesus answered them and said, "Most assuredly, I say to you, you seek Me, not because you saw the signs, but because you ate of the loaves and were filled. Do not labour for the food which perishes [and you need this bread every day], but for the food which endures to everlasting life, which the Son of Man will give you, because God the Father has set His seal on Him." Then they said to Him, "What shall we do, that we may work the works of God?" Jesus answered and said to them, "This is the work of God, that you believe in Him whom He sent. [that is there is nothing you can do]" John 6:26-29
For this is the will of my Father, that everyone who looks on the Son and believes in him should have eternal life, and I will raise him up on the last day." John 6:40
Jesus said to him, "I am the way, the truth, and the life. No one comes to the Father except through Me. "If you had known Me, you would have known My Father also; and from now on you know Him and have seen Him." John 14:6-7
Nor is there salvation in any other, for there is no other name under heaven given among men by which we must be saved." Acts 4:12
Yet indeed I also count all things loss for the excellence of the knowledge of Christ Jesus my Lord, for whom I have suffered the loss of all things, and count them as rubbish, that I may gain Christ and be found in Him, not having my own righteousness, which is from the law, but that which is through faith in Christ, the righteousness which is from God by faith; Philippians 3:8-9
But these [book of John] are written that you may believe that Jesus is the Christ, the Son of God, and that believing you may have life in His.
