And Melchizedek king of Salem brought forth bread and wine: and he was the priest of the most high God.  And he blessed him, and said, Blessed be Abram of the most high God, possessor of heaven and earth:  And blessed be the most high God, which hath delivered thine enemies into thy hand. And he gave him tithes of all.
Deuteronomy 8:11-16…Don’t forget where you were when the Lord brought you out.
2 Corinthians 1:20
For all the promises of God in him are yea, and in him Amen, unto the glory of God by us.
The Word of God is the will of God. A “Will and Testament” is not activated until the death of that person occurs. Jesus is the only one who died to activated His will, then got up from the dead to be the mediator of His own will. His Word is His will for our lives. When we pray or speak it over ourselves and others, He mediates it in heaven.
Jesus has spoken Words over the life of every believer
Psalmist – You
 He that dwelleth in the secret place of the most High shall abide under the shadow of the Almighty.  I will say of the Lord , He is my refuge and my fortress: my God; in him will I trust.
Mediator/High Priest – Jesus
 Surely he shall deliver thee from the snare of the fowler, and from the noisome pestilence.  He shall cover thee with his feathers, and under his wings shalt thou trust: his truth shall be thy shield and buckler.  Thou shalt not be afraid for the terror by night; nor for the arrow that flieth by day;  Nor for the pestilence that walketh in darkness; nor for the destruction that wasteth at noonday.  A thousand shall fall at thy side, and ten thousand at thy right hand; but it shall not come nigh thee.  Only with thine eyes shalt thou behold and see the reward of the wicked.  Because thou hast made the Lord , which is my refuge, even the most High, thy habitation;  There shall no evil befall thee, neither shall any plague come nigh thy dwelling.  For he shall give his angels charge over thee, to keep thee in all thy ways.  They shall bear thee up in their hands, lest thou dash thy foot against a stone.  Thou shalt tread upon the lion and adder: the young lion and the dragon shalt thou trample under feet.
The Most High – God
 Because he hath set his love upon me, therefore will I deliver him: I will set him on high, because he hath known my name.  He shall call upon me, and I will answer him: I will be with him in trouble; I will deliver him, and honour him.  With long life will I satisfy him, and shew him my salvation.
 And such as do wickedly against the covenant shall he corrupt by flatteries: but the people that do know their God shall be strong, and do exploits .
Wherefore, holy brethren, partakers of the heavenly calling, consider the Apostle and High Priest of our profession, Christ Jesus;
Give Jesus words he can mediate.
