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].

No one who has been [spiritually] conceived [and eventually born] by God continues to live a sinful life, because God's seed [i.e., His word, See Luke 8:11] continues to live in his heart, so he cannot [continue a life of] sin, because he has been conceived by God.

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.

The person who has the Son [in his heart] possesses this "life;" the one who does not have the Son of God does not possess this "life."

We know that every person who has been [spiritually] conceived [by God and eventually born] does not continue in [a life of] sin, but God's one and only conceived [Son] keeps him [from continuing to sin], and the evil one [i.e., Satan] does not continue to touch him [i.e., continue to control his life].

We [apostles] proclaim to you [the truth about Jesus], who existed from the beginning [of time]. We have heard [Him] and seen [Him] with our [own] eyes. We looked at Him, and [even] touched Him with our hands. [See John 20:20]. [So, we proclaim that] He is the word of life [i.e., the life-giving Word]!

Truly, this "Life" was made known to us and we have [actually] seen it [i.e., Him], and so we testify and proclaim to you [that He is] "the Eternal Life," who was with the Father and was made known to us [apostles].
