Everyone who hears these words of mine and puts them into practice is like a wise man who built his house on the rock. The rain came down, the streams rose, and the winds blew and beat against that house; yet it did not fall, because it had its foundation on the rock. But everyone who hears these words of mine and does not put them into practice is like a foolish man who built his house on sand. The rain came down, the streams rose, and the winds blew and beat against that house, and it fell with a great crash.
Matthew 7:24-27 NIV

Do not think that I have come to abolish the Law or the Prophets; I have not come to abolish them but to fulfill them. 
Matthew 5:17 NIV

Be careful not to practice your righteousness in front of others to be seen by them. If you do, you will have no reward from your Father in heaven.
Matthew 6:1 NIV

If you forgive other people when they sin against you, your heavenly Father will also forgive you. But if you do not forgive others their sins, your Father will not forgive your sins.
Matthew 6:14-15 NIV

Do not store up for yourselves treasures on earth, where moths and vermin destroy, and where thieves break in and steal. But store up for yourselves treasures in heaven, where moths and vermin do not destroy, and where thieves do not break in and steal. For where your treasure is, there your heart will be also.
Matthew 6:19-21 NIV

You parents—if your children ask for a loaf of bread, do you give them a stone instead? Or if they ask for a fish, do you give them a snake? Of course not! So if you sinful people know how to give good gifts to your children, how much more will your heavenly Father give good gifts to those who ask him. Do to others whatever you would like them to do to you. This is the essence of all that is taught in the law and the prophets...
Matthew 7:9-12 NLT
