"Beware of practicing your righteousness before other people in order to be seen by them, for then you will have no reward from your Father who is in heaven. "Thus, when you give to the needy, sound no trumpet before you, as the hypocrites do in the synagogues and in the streets, that they may be praised by others. Truly, I say to you, they have received their reward. But when you give to the needy, do not let your left hand know what your right hand is doing, so that your giving may be in secret. And your Father who sees in secret will reward you.
As is the case in so many areas, Christians are to be different than others. Our good deeds are to be done so that God gets the glory, not us. We do not need to be flashy in our good deeds. We need to practice them so that others see God, not us. Also, notice, that Jesus does not leave any doubt about helping the needy. We are expected to help those in need. This may extend beyond financial needs. Sometimes people need a shoulder to cry on. Sometimes they need someone to mow their lawn. Sometimes they need money. Helping others is part of the Christian life. God will reward us.
