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.
And this is the promise that He has promised us—eternal life.
1 John 2:25
For the wages of sin is death, but the gift of God is eternal life in Christ Jesus our Lord.
My sheep hear My voice, and I know them, and they follow Me. And I give them eternal life, and they shall never perish; neither shall anyone snatch them out of My hand.
“Most assuredly, I say to you, he who hears My word and believes in Him who sent Me has everlasting life, and shall not come into judgment, but has passed from death into life.
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.
1 John 5:11-13
