Book of 1 John Chapter 3 Vs. 21

 Love One Another

1 John 3:21 "Beloved, if our heart condemn us not, [then] have we confidence toward God."

Beloved

The affectionate address is suggested by the preceding thought of tormenting self-accusation.

if our heart... Greek: kardia. Translated heart 160 times.

confidence toward God... Love vanishes self-condemnation. When a Christian recognizes in his life the manifestation of love in deeds and actions, it results in confidence about his relationship with God.

confidence (παῤῥησίαν)

Rev., boldness. See on 1Jhn. 2:28.

This is just saying, we have a clear conscience. The very thing that was never settled, when a person sacrificed for sin in the Old Testament, was that their conscience was never clear. The sin was covered, not done away with.

Jesus abolished our sin and gave us a clear conscience. If we know in our heart that we have done the right thing, then we can stand before Jesus on judgment day with a clear conscience.

Once a condemning heart has been silenced by resting on God’s knowledge of all things, there comes a new confidence before God. Confidence here translates parrēsia, which John had not used since his thematic statement in 1Jhn. 2:28 (cf. 1Jhn. 4:17; 1Jhn. 5:14).
