Who is the focus of these verses? It's the "chosen of God", Christians. We need to be reminded of how to relate to other Christians. So often it is family members who hurt us most, and it is no different in the body of Christ. We need to be reminded to be compassionate, kind, humble, gentle and patient. We need to be told to "bear" with one another. That word promises hardships, difficulties, pain. How do we forgive someone we have to "bear"? By remembering what we did to Jesus. Nothing anyone does to us is nearly so tragic as being nailed to a cross. We're not innocent. If we need to forgive someone, we first need to examine how we acted towards that person in whatever situation it is we're forgiving. Were our words perfect? How about our actions? Our thoughts? By whose standards? Ours, or God's? Turn your attention for a moment from the one you need to forgive, and seek within yourself first. Forgiveness comes easier then. "And beyond all these things put on love, which is the perfect bond of unity." Forgive in love, with no pride or self involved at all.
Just like Jesus.
