The unchangeableness of His purpose and it is impossible for God to lie.
Hebrews 6:17-18 God desiring even more to show to the heirs of promise the unchangeableness of His purpose, interposed with an oath, in order that by two unchangeable things, in which it is impossible for God to lie, we may have strong encouragement, we who have fled for refuge in laying hold of the hope set before us. This hope we have as an anchor of the soul, a hope both sure and steadfast and one which enters within the viel, where Jesus has entered as a forerunner for us.
From Genesis 3 to Revelations, God's purpose is to restore man to God's presence, enter within the veil, and walk beside him again. We have entered an age where everyone is right in their own eyes. Each version is at odds with the other. God's Word is the plumb line by which all truth is measured. A plumb line is a weight suspended from a string used as a vertical reference line to ensure a structure is centered. God cannot lie; he can't do so; therein lies the power of His Word. Time is a fixed entity set for a season and always moving forward. God exists outside of time. God's purposes for man are unchangeable and arranged for a season of salvation as a test of man's free will. There is no variation or shifting of shadows for God's steadfast plan. All things being possible for God ( Phil 4:13, Matt 19:26) is predicated on a few impossibilities concerning His nature. God is the plumb line by which truth is and will be measured. God exists outside of time. He is the Alpha and Omega. Imagine God holding the ribbon of time, the beginning in one hand to the end in the other. He surveys all of the time, simultaneously.
God loves your soul like the soil loves the tree. God's Word is the soil where we firmly root our faith. The soil gives the tree all the space it needs to grow. God's will is His Word. It is not a roadmap but a relationship. God is more interested in what you become than what you do. Colossians 1:9. Having received Christ Jesus as Lord, you are: firmly rooted, grounded, built up in Him, and overflowing with gratitude- one faith, one hope, one Lord. Comfort comes by knowing that you are firmly rooted.
