Proverbs 6:6-8 says ants know how to find out its food and how to save even for future. It can also separate sweet from sand even if they are mixed. Jesus knew verses attributed to God suggesting HE ordered genocide, sanctioned divorce for all petty reasons etc but he simply said they are all from human sources, not from God. (Mathew 5:43-48; 19:4-8)
Similarly, when you see absolutely true statement such as ‘God is impartial to all of His children’ (Deuteronomy 10:17; Romans 2:11) you should know that all verses contradicting this truth [i.e. God shows partiality to prayers of some] are all from human source. After saying ‘God made mankind in His image’ in Genesis 5:1, in the very next chapter when you read ‘God repented of making mankind as their tendency is towards evil, hence I am going to wipe out them from earth except one family’ (Genesis 6) you should know that this account is God-dishonoring and dismiss it. Contradictory verses would creep in–this has been foretold (Mathew 13:24-30; Acts 20:28-30) Such contradictory verses are to be treated like verses such as 1 John 5:7; Mark 16:9-20; John 8:2-11 (My Favorite Passage that’s Not in the Bible) Another example, DISFELLOWSHIP ARRANGEMENT is not from God. (Mathew 5:43-48; 1 Thessalonians 5:14, 15) And when you find verses contradicting them, you should list them as anti-Christ, anti-God, and anti-Paul verses.
