Psalm 37:21

"The wicked borrows but does not pay back, but the righteous is generous and gives..."

Unfortunately, these two principles may not necessarily differentiate between those who utterly reject God and those who claim to follow Him. Those who are made righteous by believing in Jesus are called to be generous, and should freely give of the resources God has entrusted to them...however, this doesn't always happen. Let us draw near to God so He can change our hearts. When this happens, our habits will change as well, and others will be able to see clearly what God has done in our lives. All of this is for His glory.

Peace.
