Here's a quote from my pastor, Richard C. Caldwell, Jr.
"Never take your sins lightly. If we do so, we're treating lightly the suffering of Jesus on the cross. God's grace never encourages anyone to continue in sin. God's grace forgives sins and sets people free from their sins...not sinless perfection, but turning from sin to a new lifestyle."
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, ESV
