'Never ending' in the Bible

And this is the promise which Christ [or, "God"] has given to us: [It is] never ending life. [Note: This passage may mean that God promised us "the Eternal Life," that is, Christ, See John 3:16].

Every person who hates his brother is a murderer [in God's sight]; and you [surely] know that no murderer has [the hope of] never ending life remaining in his heart.

And this is the testimony [of God]: He gave to us [the hope of] never ending life, and this life is [available through fellowship] in His Son.

I have written these things to you people, who believe in the name [i.e., in the person and work] of the Son of God, so that you can have assurance that you have [the hope of] never ending life. [See Titus 1:2; 3:7; Mark 10:30].
