Matthew 6:3-4, 6, 18
3 But when you give to someone in need, don’t let your left hand know what your right hand is doing. 4 Give your gifts in private, and your Father, who sees everything, will reward you.
6 "When you pray, go into your room. Close the door and pray to your Father, who can't be seen. He will reward you. Your Father sees what is done secretly.
16 "When you go without eating, do not look gloomy like those who only pretend to be holy. They make their faces very sad. They want to show people they are fasting. What I'm about to tell you is true. They have received their complete reward. 17 "But when you go without eating, put olive oil on your head. Wash your face. 18 Then others will not know that you are fasting. Only your Father, who can't be seen, will know it. He will reward you. Your Father sees what is done secretly.
Jesus says we should check our motives in three areas: generosity (Matt 6:4), prayer (Matt 6:6), and fasting (Matt 6:18). Those acts should not be self-centered, but God-centered, done not to make us look good but to make God look good. The reward God promises is not material, and it is never given to those who seek it. Doing something only for ourselves is not a loving sacrifice. With your next good deed, ask, "Would I still do this if no one would ever know I did it?" (Life Application Study Bible, 9/12/12)
I pray these simple reminders bring us all closer to God.
