1 Take care not to practice your righteousness in the sight of people, to be noticed by them; otherwise you have no reward with your Father who is in heaven.
2 So when you give to the poor, do not sound a trumpet before you, as the hypocrites do in the synagogues and on the streets, so that they will be praised by people. Truly I say to you, they have their reward in full. 3 But when you give to the poor, do not let your left hand know what your right hand is doing, 4 so that your charitable giving will be in secret; and your Father who sees what is done in secret will reward you.
And when thou prayest, thou shalt not be as the hypocrites are: for they love to pray standing in the synagogues and in the corners of the streets, that they may be seen of men. Verily I say unto you, They have their reward. But thou, when thou prayest, enter into thy closet, and when thou hast shut thy door, pray to thy Father which is in secret; and thy Father which seeth in secret shall reward thee openly.
14 For if you forgive other people for their offenses, your heavenly Father will also forgive you. 15 But if you do not forgive other people, then your Father will not forgive your offenses.
I like to quote Matthew 6:5-6 to them too.
keeps getting better the further you read:
That’s not Republican Jesus!
