For thus says the Lord GOD, the Holy One of Israel:
“In returning and rest you shall be saved;
in quietness and confidence shall be your strength.”
i. Trusting God’s promise means returning (repentance). If there is conspicuous disobedience in our lives, we must return to the LORD’s ways. Outright disobedience is never consistent with real trust in God’s promise. Returning also has the idea of drawing close to the LORD.
ii. Trusting God’s promise means rest. When we trust God, we don’t have to strive for ourselves. We don’t have to run all about trying to protect or guard ourselves. We have the best Protector, the best Guard in God. We can rest in Him, and when we do, it shows we are really trusting in God’s promise.
iii. Trusting God’s promise means quietness. You don’t need to argue for your side when God is on your side. Be quiet before Him and before others. It shows that you really trust Him.
iv. Trusting God’s promise means confidence. You aren’t given to despair or fear, because you trust God’s promise. You know He can and will come through, and you have a profound confidence in the God who loves you.
v. All of these things together mean a real trust in God’s promise, and it means that we shall be saved, and it means that we will find strength. There is no person walking this earth more powerful than a child of God boldly and properly trusting the promise of the living God!
