But now hath he obtained a more excellent ministry, by how much also he is the mediator of a better covenant, which was established upon better promises. Hebrews 8:6 (KJV) emphasis mine

God has promised us better things based on who Jesus is and what He does. It is based on a better covenant and promises. We have the guarantee of a better life, beter days ahead. God’s plan is for our lives to get better and better the longer we live.

Jesus has an excellent ministry in which he mediates His covenant and promises. In other words, Jesus helps to bring His Word to pass in our lives as we agree with Him. Jesus Himself helps us to believe the promises of God so we can take advantage of the covenant contract He made with God the Father. And Jesus provides all we need, now and forever.

My friend, as we claim who Jesus is, what He has done, and what He will do for us, we cannot lose, fail, or be defeated. As we claim all Jesus provided, God will make sure our lives turn out right, just the way He planned for them to go.

For we are God’s [own] handiwork (His workmanship), recreated in Christ Jesus, [born anew] that we may do those good works which God predestined (planned beforehand) for us [taking paths which He prepared ahead of time], that we should walk in them [living the good life which He prearranged and made ready for us to live]. Ephesians 2:10 (Amplified Bible Classic Edition, AMPC)

Hebrews 7:22 says that by so much was Jesus made a surety, or a guarantee, of a better testament, or covenant. That covenant is our contract with God. Jesus is our guarantee of a better life. Just as Jesus was raised from death, so will your life be resurrected and you will walk in newness of life.
