Learn to do good;
Reprove the ruthless,
[g]Defend the orphan,
Plead for the widow. (Isaiah 1:17 NASB)
Here we see the positive good that the children of Israel are required to do before God will forgive them for their past sins. These good deeds mentioned above are obviously very important, however, they are not enough to remove the guilt of the sinner. The person who does these things are promised forgiveness because God said that he will give grace to those who repent. Those who do good are saved by the power of God, not by the power of their own good works. The good works signify their acceptance of and genuine desire for God’s healing grace.
