For the grace of God has appeared, bringing salvation for all people, training us to renounce ungodliness and worldly passions, and to live self-controlled, upright, and godly lives in the present age, waiting for our blessed hope, the appearing of the glory of our great God and Savior Jesus Christ, who gave himself for us to redeem us from all lawlessness and to purify for himself a people for his own possession who are zealous for good works.

Titus 2:11-14

When God’s forgiveness and acceptance have freed us from fear and pride and greed, we are filled with a zeal to love others the way we have been loved. We risk our possessions and our lives since we are secure in Christ. When we love others like this, our behavior is contrary to human self-enhancement and self-preservation. Attention is thus drawn to our life-transforming Treasure and Security, namely, God.

And what are these “good works”? Without limiting their scope, the Bible means mainly helping people in urgent need, especially those who possess least and suffer most. For example, the Bible says, “Let our people learn to devote themselves to good works, so as to help cases of urgent need” (Titus 3:14). Christ died to make us this kind of people—passionate to help the poor and the perishing. It is the best life, no matter what it costs us in this world: They get help, we get joy, God gets glory.
