In God's presence, before the tabernacle at church or in the dark of a quiet night, think of someone you have difficulty forgiving. Be totally open and not holding back anything, ask God to show you clearly the problem. If you were partly at fault, admit it. Putting all pride aside, ask God for the courage to bring about reconciliation. Then follow up! In the case you cannot contact the person anymore, at least pray for God's blessings on the person and forgive him or her from the bottom of your heart for the glory of God. If you experience great freedom and peace afterwards, then you'll know that you have passed this test of obedience. Rejoice because you have overcome yourself and greatly pleased God.
