Jeremiah can not be clearer than he is in this declaration.
If God heals us, we are healed.
If God saves us, we are saved.
Why?
Because He is our praise. He is ultimately in control. He is God, all powerful, all knowing.
Job reminds us that God “can do all things, and that no purpose of [God’s] can be thwarted.” (Job 42: 2) The psalmist sings, “The Lord will fulfill His purpose for me.” (Psalm 138: 8) God Himself declares, “My counsel shall stand and I will accomplish all My purpose… I have spoken, and I will bring it to pass; I have purposed, and I will do it.” (Isaiah 46: 10, 11)
“Listen to Me, you stubborn of heart, you who are far from righteousness: I bring near My righteousness; it is not far off, and My salvation will not delay.” (Isaiah 46: 12 – 13)
“Salvation belongs to the Lord.” (Psalm 3: 8)
