A Man Above Reproach
There will always be some "outliers" that will criticize, judge, condemn, or act against us no matter what we do. Jesus experienced this and was accused of being a drunkard and demon possessed despite His sinless and loving intentions and actions. Saul was jealous of David and hunted him down even though his intentions were honorable and he only wanted to serve his king and his God faithfully. Trials and difficulties will come (Matthew 5:10-12, 2 Timothy 3:12) as we live in and for Christ. The point is to not live or act in ways which are worthy of those accusations or reactions. Jesus reminds us to Love God and others according to the truth of His Holy Word and the leading of His Holy Spirit (Luke 10:27, Galatians 5:22). Paul tells us to live in peace with everyone (Romans 12:18, Hebrews 12:14) to the best of our Spirit led ability but recognizes that some may choose to respond otherwise. Keeping short accounts with God and people is helpful here. This requires coming before God (Psalm 139:23-24) to ask Him if there is any truth or justification for any such accusations or reactions that we may or may not be aware of. If the answer is yes, then I must own my sin, confess and ask for forgiveness from God and man, and seek God's help to turn from this behavior. If the answer is no, then we might humbly and privately ask the person why they hold that position and then listen intently for the reason and the key to restoring the relationship (so far as it depends on us). Doing this will keep us in fellowship with God more consistently, will keep our conscience clear, and will free us up from trying to "manage" our reputations. Proverbs 3:1-4 promises peace and a good reputation with God and others if we consistently submit ourselves to the authority of God's Word and allow His Holy Spirit to transform us so that we regularly demonstrate love and faithfulness in our relationships and responsibilities.
