And let us not lose heart and grow weary and faint in acting nobly and doing right, for in due time and at the appointed season we shall reap, if we do not loosen and relax our courage and faint. —Galatians 6:9
The Word says, Let each one of us make it a practice to please (make happy) his neighbor for his good and for his true welfare, to edify him [to strengthen him and build him up spiritually] (Romans 15:2).
This tells me that we need to have our mind full of ways to bless people. Early in the day, think up something you want to do to bless someone. Think up something you can do to surprise somebody or to make somebody happy. You will be amazed at how quickly the Lord leads you to something good you can do for someone. Joy comes from giving on His behalf.
