Everyone who hates (works against) his brother [in Christ] is [at heart] a murderer [by God’s standards]; and you know that no murderer has eternal life abiding in him.

I have written to you, fathers, because you know Him who has existed from the beginning. I have written to you, young men, because you are strong and vigorous, and the word of God remains [always] in you, and you have been victorious over the evil one [by accepting Jesus as Savior].

Whoever confesses and acknowledges that Jesus is the Son of God, God abides in him, and he in God.

As for you, the anointing [the special gift, the preparation] which you received from Him remains [permanently] in you, and you have no need for anyone to teach you. But just as His anointing teaches you [giving you insight through the presence of the Holy Spirit] about all things, and is true and is not a lie, and just as His anointing has taught you, you must remain in Him [being rooted in Him, knit to Him].

Children, it is the last hour [the end of this age]; and just as you heard that the antichrist is coming [the one who will oppose Christ and attempt to replace Him], even now many antichrists (false teachers) have appeared, which confirms our belief that it is the last hour.
