But love your enemies, do good, and lend, hoping for nothing in return; and your reward will be great, and you will be sons of the Most High. For He is kind to the unthankful and evil. (Luke 6:35 NKJV)
God loves to give you gifts. The gift that God most likes to give is His grace to you. When you least expect it, and when you know for sure that you are not worthy. God loves to forgive and bless you. You should see the look on His face when you receive His grace. Your reaction is a joy for God.
God wants you to do likewise to those around you. In fact, that is one thing God requires of you to forgive others as He has forgiven you. The next time someone does something mean to you, don’t respond in kind. Rather, go out of your way to astound him with something he doesn’t deserve: grace. His grace is greater than all your sins.
