Matthew 6:1-4 (NASB)

Beware of practicing your righteousness before men to be noticed by them; otherwise you have no reward with your Father who is in heaven.

2 “So when you [a]give to the poor, do not sound a trumpet before you, as the hypocrites do in the synagogues and in the streets, so that they may be honored by men. Truly I say to you, they have their reward in full. 3 But when you [b]give to the poor, do not let your left hand know what your right hand is doing, 4 so that your [c]giving will be in secret; and your Father who sees what is done in secret will reward you.

Our Lord next warned against hypocrisy and outward show in religious duties. What we do, must be done from an inward principle, that we may be approved of God, not that we may be praised of men. In these verses we are cautioned against hypocrisy in giving alms. Take heed of it. It is a subtle sin; and vain-glory creeps into what we do, before we are aware. But the duty is not the less necessary and excellent for being abused by hypocrites to serve their pride. The doom Christ passes, at first may seem a promise, but it is their reward; not the reward God promises to those who do good, but the reward hypocrites promise themselves, and a poor reward it is; they did it to be seen of men, and they are seen of men. When we take least notice of our good deeds ourselves, God takes most notice of them. He will reward thee; not as a master who gives his servant what he earns, and no more, but as a Father who gives abundantly to his son that serves him.

When I serve, I must serve with my heart to God.
When I give to poor, it is to glorify God and not myself.

When I do good, I should not do good for because I want to hear people to praise me,but to do the works of God.( Righteousness) 

When I do good, there must be no motive.

God sees the heart, the inward principle. God doesn't see the outward doing.

I am not to be a hypocrite, God doesn't wants us to be that. God wants us to be pure and innocent and a heart of serving.

When we do the acts of God, doing His way, We are showing a Christ-like ( Jesus ) person to the world.
Through Christ, When I do the works of God, I must do to glorify God and show an example to the people around me. So  that people will see Christ in me.

Dear Heavenly Father,

I pray that You will help me to renew my heart, a heart of serving You.

Lord, I pray that when I serve others I do it to glorify You and not myself.

Lord, I give thanks to You for what You've done on the cross.

Help me to become more like Jesus, to be Christ-like.

Thank You Lord,

In the name of Jesus.

Amen !
