"What if some did not believe and were without faith? Does their lack of faith and their faithlessness nullify and make ineffective and void the faithfulness of God and His fidelity [to His Word]? By no means! Let God be found true though every human being be false and a liar." (Romans 3:3-4, The Amplified Bible)
Everything that has to do with men, everything in this natural world, is subject to change, but the Word of God is not.
The Word of God is true even when everything else around you is telling you otherwise. But notice that Romans 3:3-4 says you must let God be true in your life.
To do so, you must forever settle in your heart and mind that there is no fault in God. There is no shadow of turning in Him. There’s no weakness or shortcoming in His Word.
You will never catch God in a lie. You will never get in a situation where you exercise faith in God’s Word and God fails to keep that Word. Never! The Bible says that God is active and alert, watching over His Word to perform it (Jeremiah 1:12, The Amplified Bible).
Understand, however, that it’s not enough just to know what the Word says. It must be reality to you—more real than the problem you face.
For example, maybe you or your children have experienced recurring symptoms of an illness for a long time. If so, you need to sit down and ask yourself, Do I really believe that according to 1 Peter 2:24, by His stripes we were healed?
However you honestly answered that question in your heart makes the difference in your situation. You have to choose to believe that God cannot lie and that His Word is true...regardless of what the circumstances are telling you. You cannot attempt to exercise your faith in His Word based on head knowledge. That’s not enough!
That’s why we must constantly center ourselves on God’s Word, because it’s that Word that produces faith in our hearts. In fact, you cannot deepen your faith in God without deepening your trust in His Word. Let God be found true...if you believe in His Word, it will come to pass.
