1 John 4:13-18

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