"I saw the angel in the marble and carved until I set him free.” (Michael Angelo)
Try the same attitude with the Bible, all confusions will be cleared. Bible is like a marble piece which contains both—words of ordinary characters and words of real prophets who were linked with God, and these two groups are often opposed to each other (Mathew 23:37; Jeremiah 20:3) as the ordinary characters are often pleasure-oriented and prophets are truth-oriented. Prophets are true even when they speak about future. (missed-opportunity-jehovahs-witnesses). Hence if you take only sayings of the real prophets (1-thessalonians/5/19-23), then you have the truth.
For example,
1) According to matthew/5/43-48; Isaiah-66-3 all killings supposedly ordered by God belong to human writers, not to God.
2) According to james/1-13 all accounts in which God supposedly “tested” people are from human writers, not from God.
3) According to God’s own testimony, King David never erred in any matter (1KI.14.8). That means all derogatory accounts about David such as his adultery, murder etc belong to envious human writers, not to God. So is the case with apostle Paul who was “holy, righteous and blameless” (1-thessalonians/2/4-10) and had freeness of speech to tell others to be “blameless” like him (1 Thessalonians 5:19-23; Ephesians 5:24). That means verses such as Romans 7:19 do not belong to Paul, but to someone envious of Paul. Similarly, verses such as Galatians 6:5, 7; 2 Corinthians 9:6 reflect the mind of Christ (Mark 4:24; Mathew 12:32) Hence all verses contradictory to such absolute statements cannot be from Paul, but from someone envious of Paul.
4) The verses that show Apostle Peter disowned Jesus belong to human writers, not to God. Because, if apostle Peter had really disowned Jesus, his contemporaries would have interrupted him when he rebuked Jews, saying: “You disowned the Holy and Righteous One and asked that a murderer be released to you.“ (Acts 3:14) His listeners would have asked him “What right do you have to reprove us for ‘DISOWNING Jesus” when you yourself have done it first?” All such verses or accounts were later adoptions. (2 Timothy 4:3)
Now you know which verses in the Bible belong to human writers and which verses belong to God and His prophets. No confusion at all. (Daniel 12:10) Also see https://www.jehovahs-witness.com/topic/5915507227099136/new-world-translation-much-different-other-translations
