It is much easier to forgive if you have experienced the wonderful forgiving power of Jesus. When you come face to face with the holiness/perfection of God you suddenly realise how wretched we ALL are in God's sight in comparison with HIS absolute glory. The fact that Jesus suffered God's wrath (in our place) for the terror of our sinful nature so that we can receive HIS forgiveness enables us to forgive others. Jesus said that if (after all this forgiveness) if we still do not forgive those who fail us (a much lower debt in comparison) we cease to benefit from God's forgiveness.
