"Be merciful, just as your Father is merciful." (Luke 6:36)
As humans we are prone to forget many things. Everyone has walked out the home and realized at some point they forgot their keys to the car. Also in spiritual life we are prone to forget things that God speaks to us or does for us. When we are in a situation where we are hurt we are prone to react in a way that is not like how God treated us. When God forgives us, He forgets. When we forgive, we continue to talk about the problem or bring back peoples sins when it is convent for us. The Scripture passage does not tell us to be "angry" as God is angry, or to be judging as God will judge the motives of all men's hearts one day (1 Corinthians 4:5). Rather it says for us to be "merciful."
Life affords us many opportunities to be merciful to others, though we have great reasons to accuse or condemn, God's calling on our lives is to forgive and show mercy. The season of Lent is coming up in the Church calendar. This could perhaps be a time to think each day of how to be merciful to others in your life. We all need forgiveness and mercy daily from God, why not share that grace to others in your life? The prodigal son deserved only judgement for his foolish decisions but the character of God in the Father shows how mercy He is in embracing the son and rewarding him, though undeserving. When we celebrate Communion, when we daily pray "forgive us our trespasses" (Matthew 6:12) daily, let us feel God's mercy and share that mercy with others. There are many ways to grow in Christ-likeness and mercy is one of them. Let us not forget mercy triumphs over judgment (James 2:13).
