14 For if you forgive other people when they sin against you, your heavenly Father will also forgive you. 15 But if you do not forgive others their sins, your Father will not forgive your sins.
From Luther’s Small Catechism explanation of the Lord’s Prayer:
And forgive us our trespasses as we forgive those who trespass against us.
What does this mean?
We pray in this petition that our Father in heaven would not look at our sins or deny our prayer because of them. We are neither worthy of the things for which we pray, nor have we deserved them, but we ask that He would give them all to us by grace, for we surely sin much and truly deserve nothing but punishment. So too we will sincerely forgive and gladly do good to those who sin against us.
Don't lose sight of these words about forgiveness – in this moment of devoting with God – and in light of another of Jesus' teachings: "If you love Me, you will obey what I command".
Father, forgive me my trespasses as I forgive those who trespass against me. Forgive me my debts as I forgive my debtors. Forgive me my sins as I forgive those who have sinned against me. In Jesus' name I pray. Amen.
Read the verses of the Psalm.
Mark the words or phrases that catch your attention.
Meditate: talk (or better, write) with God about those words. Ask Him to impress things upon your heart and mind; expect responses.
Consider the Psalmist’s point: He (or you!) could fall asleep thinking of God’s vast thoughts – counting them as grains of sand. One could fall asleep and then pick up again in the morning, never exhausting the thoughts of God.
