Have literally been camped out in Philippians 1:27 thru 2:7 for the last week. So much there.
Philippians 2:2-3 (ESV) 2 complete my joy by being of the same mind, having the same love, being in full accord and of one mind. 3 Do nothing from selfish ambition or conceit, but in humility count others more significant than yourselves.
Philippians 2:4-5 To discover your own completeness in Christ frees you to turn your attention away from yourself to others! 5 The way Jesus saw himself is the only valid way to see yourself! The Mirror
Living this way makes it impossible to have unforgiveness towards someone.
