Herein is our love made perfect, that we may have boldness in the day of judgment: because as he is, so are we in this world.
(Compare 1 John 3:19-21.)
Our love, х hee (G3588) agapee (G26) meth' (G3326) heemoon (G2257)]. 'LOVE is made perfect (in its relations) with us.' Love dwelling in us advances to its consummation 'with us;' i:e., as it is concerned with us (Luke 1:58, "showed great mercy upon (with) her:" 2 John 1:2.)
Boldness - `confidence' х parreesian (G3954)]: parallel to 1 John 3:21; opposite to "fear," 1 John 4:18. Herein is love perfected, namely, in God dwelling in us, and our dwelling in God (1 John 4:16) involving as is result, 'that we can have confidence (boldness) in the day of judgment' (so terrible to other men, Acts 24:25).
Because ... The ground of our 'confidence' is, 'because even as He (Christ) is, we also are in this world' (He will not, in that day, condemn those like Himself; we are righteous as He is righteous, especially in that which is the sum of righteousness, love (1 John 3:14). Christ IS righteous, and love itself, in heaven: so are we, His members still "in this world." Our oneness with Him even now in His exaltation (Ephesians 2:6), so that all that belongs to Him of righteousness etc., belongs to us by perfect imputation, and progressive impartation, is the ground of our love being perfected, so that we can have confidence in the day of judgment. We are in, not of, this world.
