SALVATION IS NOT A LICENSE TO SIN

Salvation gives us deliverance from the power of sin and Spiritual death. But we still suffer the consequences of our sin, just as David suffered for His sins, but he did entered the Kingdom. Because David repentance was true and he turned away from all that separated him from God. 

Matthews 5:17 Jesus declared, think not that I am came to destroy the law.... The Apostle John also taught throughout his writing that the Laws are still to be observed by God's people. Jesus did not give His life to free us, so that we could live in sin, and just say forgive me and keep it moving.

God comendments were not transfer to the New Testament to take up space. They were put there as instructions on how to follow Jesus and serve our purpose. Jesus died to give us salvation to release us from the power of sin, so that we may repent and turn away from our old self and be forgiven. That's it in a nutshell, now for those that want to rebuttal this, please do it with scripture not with your words.

The Lord is my shepherd; I shall not want. He maketh me to lie down in green pastures: he leadeth me beside the still waters.  He restoreth my soul: he leadeth me in the paths of righteousness for his name's sake.  Yea, though I walk through the valley of the shadow of death, I will fear no evil: for thou art with me; thy rod and thy staff they comfort me.  Thou preparest a table before me in the presence of mine enemies: thou anointest my head with oil; my cup runneth over.  Surely goodness and mercy shall follow me all the days of my life: and I will dwell in the house of the Lord for ever. Amen
