God remains. No matter what my circumstances, no matter what my mood may be, no matter if I feel His presence or feel close to Him, God remains.
He is unchanging. My life is one of change.
His truth is truth. My truth, if I choose to follow it, adjusts according to my latest whim or gain of knowledge.
God knows all. Any increase of knowledge that I may have is no surprise to Him. And it doesn’t change His truth.
What is His truth? He created the heavens and the earth. The heavens tell of the glory of God; and their expanse declares the work of His hands (Psalm 19:1).

The earth, my limited home, is His footstool.
And yet, He values me. So do not fear; you are more valuable than a great number of sparrows (Matthew 10:31).
God created me. And He longs for me. He will exult over you with joy, He will be quiet in His love, He will rejoice over you with shouts of joy (Zephaniah 3:17).
He made a way. He made a way for fellowship between me and Him. I in them and You in Me, that they may be perfected in unity, so that the world may know that You sent Me, and loved them, even as You have loved Me (John 17:23). But God demonstrates His own love toward us, in that while we were yet sinners, Christ died for us (Romans 5:8). He made a way through Christ.
And He knew it from the beginning. In the beginning was the Word, and the Word was with God, and the Word was God. He was in the beginning with God. All things came into being through Him, and apart from Him nothing came into being that has come into being. (John 1:1-3) …in His Son, whom He appointed heir of all things, through whom also He made the world (Hebrews 1:2).
If God had all that taken care of from the beginning, maybe, just maybe, He has me taken care of now. Because God remains. He remains unchanging.
But You are the same, and Your years will not come to an end (Hebrews 1:12).
