The seniority of Jesus over Moses is a clear indication of the greatness of grace over the law. As in Galatians 5:14 (for the entire law is fulfilled in keeping this one commandment. “Love your neighbor as yourself”). Therefore love covers/sums up the law and Love is all possible by grace.
Therefore, grace is all that sustains us through the great apostle and the high priest Jesus Christ.
From the beginning of time, Christ being the author of all things, law included, becomes the builder. Thus, just as the builder of the house has greater honor than the house itself, so then was and is that Christ is greater than Moses.
Furthermore, Moses was just a faithful servant testifying to what would be said in the future. But Jesus is the faithful son in the house of God.
He was not just found faithful due to his sonship but rather through giving up his life to face oppression and humiliation of man and made an atonement of sin for every man. And in the so doing Christ having suffered when he was tempted he is able to help those who are being tempted. This qualified him a merciful and a faithful high priest equal to the task in the house of God. Therefore earning an inheritance of the greatest name above angles and all that is above.
Unbelief is the greatest enemy to a Christian. It draws away all the goodies that life holds. Therefore, God’s intention is to have His place of rest in our Hearts. Thus, we are called to lighten/ease/release our hearts for Him (Jesus) to take his place. Hebrew 3:7 so as the Holy Spirit say: today if you hear his voice do not harden your heart as you did in the time of rebellion.
God works it out to see or to have us in his table, sharing as one family. He changes or heart to be receptive to Him (word).Ezekiel 11:19. I will give them a undivided heart and put a new heart in them. I will remove from them their heart of stone and give them a heart of flesh.
Check Ezekiel 36:26…….. I will put a new spirit in them……..
This all is a clear confirmation of God’s intention and Love that he has for human being. He is not just in the business of caring for his children but also to change the worldly into his own kingdom. To bring into their lives the reality of life. To do these he is transforming us from our old by easing our heart in accepting his Word and opening up for him to take his place in us.
A stone heart is a heart of rebellion. It contradict all the truth, clinging to the myths and decisive philosophies of men which are insights of darkness. All that rebellion holds is death, fear and fully hijacked destinies. 
Therefore brothers and sisters we are called to drawn ourselves it the righteousness of God which comes by fully trading our heart to our Lord Jesus Christ to take his place so as to lead us to the promised destiny. These is where the truth of life, the light to our destiny and the way to the eternity is.
Our ancestors perished in rebellion, therefore let’s not fall culprits of the same unbelief.

John 3:15 in order that everyone who believes in Him [who cleaves to Him, trusts Him, and relies on Him] may not perish, but have eternal life and [actually] live forever! For God so greatly loved and dearly prized the world that He [even] gave up His only begotten (unique) Son, so that whoever believes in (trusts in, clings to, relies on) Him shall not perish (come to destruction, be lost) but have eternal (everlasting) life. For God did not send the Son into the world in order to judge (to reject, to condemn, to pass sentence on) the world, but that the world might find salvation and be made safe and sound through Him.(AMP)
