What does it mean that God is merciful?
God being merciful basically means that, when we deserve punishment, He doesn’t punish us, and in fact blesses us instead. Mercy is the withholding of a just condemnation. Throughout the Bible, God gives many illustrations of His mercy. God fully demonstrates His mercy in Jesus Christ.
God was merciful to the wayward Solomon in 1 Kings 11:13. God was merciful to Israel in captivity (Psalm 106:45; Nehemiah 9:31). David illustrated God’s mercy when he showed kindness to Mephibosheth (2 Samuel 9:7). God’s mercy was illustrated every year on the Day of Atonement, when the high priest entered the Holiest Place and sprinkled the blood of the sacrifice before the mercy seat (Leviticus 16:14).
Another illustration of God’s mercy is found in Matthew 18:23–27. In this parable, Jesus describes a rich ruler who was owed a large sum of money. The ruler ordered that money be collected, but then the debtor came and begged for mercy. The ruler, in turn, graciously forgives the debt. Here’s the point: we owed God a debt we could never repay, and He has freely forgiven us that debt in Christ! Interestingly, after the ruler in the parable forgives the debt, the person who owed the money refuses to forgive someone else. The ruler then judges that ungrateful person. God requires us to be merciful and forgiving to others here on earth (see Matthew 6:15). We who have been forgiven so much have no right to withhold forgiveness from others.
Mercy is coupled with other attributes of God in Psalm 86:15, “You, O Lord, are a God merciful and gracious, slow to anger and abounding in steadfast love and faithfulness” (ESV). God’s mercy is rooted in His love for us. He is merciful, in large part, because He is love (1 John 4:8). As sinners, we deserve punishment (Romans 3:23). God’s righteousness requires punishment for sin—He wouldn’t be holy otherwise. Since God does love us and is merciful, He sent His Son (John 3:16). The fullness of His mercy is seen in Matthew 27. Jesus is brutally beaten and murdered on our behalf; Jesus received our just condemnation, and we received God’s mercy.
Because of His love for us, God wants us to be with Him. His mercy is required for that to take place; there is an inseparable connection between God’s love and mercy. Jesus laid down His life and became the sacrificial lamb (Isaiah 53:7; John 1:29) so that God’s mercy could be extended to us. Instead of punishing us for our sin, God allowed His Son to take the condemnation in our place. That is the ultimate act of God’s mercy (see Ephesians 2:4–5). To our eternal benefit, “mercy triumphs over judgment” (James 2:13b).
