and in your godliness, brotherly affection, and in your brotherly affection, [develop Christian] love [that is, learn to unselfishly seek the best for others and to do things for their benefit].

But whoever habitually keeps His word and obeys His precepts [and treasures His message in its entirety], in him the love of God has truly been perfected [it is completed and has reached maturity]. By this we know [for certain] that we are in Him:

Do Not Love the World

Do not love the world [of sin that opposes God and His precepts], nor the things that are in the world. If anyone loves the world, the love of the Father is not in him.

By this the children of God and the children of the devil are clearly identified: anyone who does not practice righteousness [who does not seek God’s will in thought, action, and purpose] is not of God, nor is the one who does not [unselfishly] love his [believing] brother.

God Is Love

Beloved, let us [unselfishly] love and seek the best for one another, for love is from God; and everyone who loves [others] is born of God and knows God [through personal experience].

The one who does not love has not become acquainted with God [does not and never did know Him], for God is love. [He is the originator of love, and it is an enduring attribute of His nature.]

By this the love of God was displayed in us, in that God has sent His [One and] only begotten Son [the One who is truly unique, the only One of His kind] into the world so that we might live through Him.

In this is love, not that we loved God, but that He loved us and sent His Son to be the propitiation [that is, the atoning sacrifice, and the satisfying offering] for our sins [fulfilling God’s requirement for justice against sin and placating His wrath].

No one has seen God at any time. But if we love one another [with unselfish concern], God abides in us, and His love [the love that is His essence abides in us and] is completed and perfected in us.

We have come to know [by personal observation and experience], and have believed [with deep, consistent faith] the love which God has for us. God is love, and the one who abides in love abides in God, and God abides continually in him.

There is no fear in love [dread does not exist]. But perfect (complete, full-grown) love drives out fear, because fear involves [the expectation of divine] punishment, so the one who is afraid [of God’s judgment] is not perfected in love [has not grown into a sufficient understanding of God’s love].

If anyone says, “I love God,” and hates (works against) his [Christian] brother he is a liar; for the one who does not love his brother whom he has seen, cannot love God whom he has not seen.

Overcoming the World

Everyone who believes [with a deep, abiding trust in the fact] that Jesus is the Christ (the Messiah, the Anointed) is born of God [that is, reborn from above—spiritually transformed, renewed, and set apart for His purpose], and everyone who loves the Father also loves the child born of Him.

For the [true] love of God is this: that we habitually keep His commandments and remain focused on His precepts. And His commandments and His precepts are not difficult [to obey].
