¹³ By this we know [with confident assurance] that we abide in Him and He in us, because He has given to us His [Holy] Spirit. ¹⁴ We [who were with Him in person] have seen and testify [as eye-witnesses] that the Father has sent the Son to be the Savior of the world.

¹⁵ Whoever confesses and acknowledges that Jesus is the Son of God, God abides in him, and he in God. ¹⁶ 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. ¹⁷ In this [union and fellowship with Him], love is completed and perfected with us, so that we may have confidence in the day of judgment [with assurance and boldness to face Him]; because as He is, so are we in this world. ¹⁸ 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]. ¹⁹ We love, because ^[a]He first loved us. ²⁰ 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. ²¹ And this commandment we have from Him, that the one who loves God should also [unselfishly] love his brother and seek the best for him.
