“If you are not firm in faith, you will not be firm at all.” Isaiah 7:9
“We must endure in our faith; in our belief and our trust in God. For the Scripture says, “…My righteous one shall live by faith, and if he shrinks back, my soul has no pleasure in Him” (Hebrews 10:38). We must endeavor to believe God and trust that He is always working all things (i.e., all the circumstances, all the relationships, and all the events of our lives) out for our good and His glory, even when this is difficult to do. We must trust God all the time – in the midst of seemingly overwhelming personal weaknesses, broken relationships, and even shameful pasts. We must stand on the solid rock of the promise of God: that He causes “…all things work together for good, for those who are called according to his purpose…” (Romans 8:28).
Believing that God will cause all things to work out for our good and His glory can be difficult when those all things include abandonment, abortion, abuse, addictions, betrayal, chronic pain, divorce, mental illness, the shame of sexual and physical assault, or the insecurity that results from prolonged emotional abuse. But, regardless of how difficult it may be for us to understand how God will overcome our painful realities and transform us through them; the Lord still calls us to believe that He can and that He will do all that He has said He would do for us. Only He expects that we believe in Him. For we know that He has said, “…without faith it is impossible to please him, for whoever would draw near to God must believe that he exists and that he rewards those who seek him” (Hebrews 11:6). Therefore, we must discipline ourselves to trust God and rely on His ability to work out His good will in our lives – no matter how impossible this may seem to be to us. In other words, we must be firm in our faith. For Isaiah 7:9 warns us, “If you are not firm in faith, you will not be firm at all.”
