Your light must shine before people in such a way that they may see your good works, and glorify your Father who is in heaven.

so that you may prove yourselves to be sons of your Father who is in heaven; for He causes His sun to rise on the evil and the good, and sends rain on the righteous and the unrighteous.

So if you, despite being evil, know how to give good gifts to your children, how much more will your Father who is in heaven give good things to those who ask Him!
