I am the resurrection and the life; he who believes in Me will live even if he dies, and everyone who lives and believes in Me will never die. Do you believe this? - Jesus Christ, John 11:25-26
Truly, truly, I say to you, He that believes on me has everlasting life. - Jesus Christ, John 6:47
Whoever believes in the Son has eternal life, but whoever rejects the Son will not see life, for God's wrath remains on them. - Jesus Christ, John 3:36
And this is the testimony: that God has given us eternal life, and this life is in His Son. He who has the Son has life; he who does not have the Son of God does not have life. These things I have written to you who believe in the name of the Son of God, that you may know that you have eternal life, and that you may continue to believe in the name of the Son of God. - John the Apostle, 1 John 5:11-13
