Colossians 3:12-14 – 12 Therefore, as God’s chosen people, holy and dearly loved, clothe yourselves with compassion, kindness, humility, gentleness and patience. 13 Bear with each other and forgive whatever grievances you may have against one another. Forgive as the Lord forgave you. 14 And over all these virtues put on love, which binds them all together in perfect unity.
We need to draw our strength from Him. Loving and forgiving those who have upset you doesn’t come naturally. But it’s only by forgiveness (of God) that we have the opportunity for the free gift of salvation. God is Love. Loving and forgiving makes things better for all of us.
