God's Mercy is a Gift
Matthew 23:23 "Woe unto you, scribes and Pharisees, hypocrites! for ye pay tithe of mint and anise and cummin, and have omitted the weightier matters of the law, judgment, mercy, and faith: these ought ye to have done, and not to leave the other undone."
One of the ways that God's goodness is revealed is by His mercy. We may describe mercy as the readiness of God to relieve the misery of fallen creatures. Many times, mercy is called compassion or lovingkindness. It is expressed toward the sinner because of the misery that sin has brought upon him.
God's mercy to the believer is revealed by God taking away the misery of sin's consequences through the New Covenant of our Savior, the Lord Jesus Christ. Mercy is not something merited or earned, but a gift, as the apostle Paul states, "Not by works of righteousness which we have done, but according to HIS MERCY He saved us" (Titus 3:5).
Paul speaks of the heavenly Father as "The Father of mercies." The word father is used many times in scripture as an originator or as a source of something. For example, the devil is called the father of lies (John 8:44), i.e. he is the author and originator of lying. Likewise, our heavenly Father is the author, originator, and source of all mercy. Each time that mankind cried out in faith, God's mercy reached out and met their need.
God is said to be rich in mercy because of His great love wherewith he loved us (Ephesians 2:4), and to have a throne called grace whereby we may come and obtain mercy. God wasn't motivated to save us through pity or a sense of obligation as our Creator. He was motivated solely by love. God loves us.
