"Through love and faithfulness sin is atoned for;
through the fear of the LORD evil is avoided.” (Proverb 16:6, NIV)
Sin can be cancelled [yə·ḵup·par] by acts of goodness such as kindness [bə·ḥe·seḏ] and faithfulness, and sin can be avoided in loving remembrance [ū·ḇə·yir·’aṯ] of God. Any individual [whether inside or outside of any organization] can do this! If a disfellowshipped person doesn’t harm anybody, but performs acts of goodness he stands “reinstated” in the heart of God. (Mathew 5:3; 25:31-40; 1 Peter 4:8; James 1:27)
Fear of God means “hatred of evil and delight in doing His will.” (proverbs/8/13) (psalm/112/1) It is also called wisdom (proverbs/9-10.htm) and righteousness. (Psalm 37:30) “To be wise [sakal]” means “to circumspect” or to act only if it would benefit self and others—showing no partiality to self or others. (daniel/12-10.htm). Root meaning of the word righteous (tsedeq, H; dikaios, G) is all about being impartial in dealing with self and others as all are same in make-up—being made in “the image of God.” Righteousness is described through life-style of righteous people. (Genesis 15:5, 6; Mathew 1:19) Abraham learned to be righteous by looking at stars, one of which is sun which sustains living beings on earth and all life-support systems such as variety of fruits and Flowers, biogeochemical cycle etc. Such loving provisions tell us to be of help to others.
It is true that certain Old Testament description about God may raise doubt about His goodness. But real prophets have removed all the untruths heaped upon God by human writers. For example, Jesus says God has only loved His enemies [which means HE has never asked anyone to kill enemies]. (matthew/5/43-48); (LUK.6.35.NIV); (exodus/21/22-23) (IIsaiah-66-3/) Jesus’ half-brother James termed many other narratives about God as untrue when he wrote ‘God has not tested anybody.’ (james/1-13.htm) Thus we are left with accounts that speak only good about God. JWs have acted unfaithfully even in their Bible translation. (https://www.jehovahs-witness.com/topic/5915507227099136/new-world-translation-much-different-other-translations) How can such ones disfellowship another? If one starts doing good, he is good to God. Hence Proverb 16:6 says the above.
