3 You will keep in perfect peace
him whose mind is steadfast,
because he trusts in you.
4 Trust in the LORD forever,
for the LORD, the LORD, is the Rock eternal.
I have written before about our need for something unshakeable to place our trust in. This passage from Isaiah speaks to that as well. We can experience peace when we trust in the Lord. Jesus Christ is the Rock of Ages and He is steady when all around us may be shaking. Hebrews says He is the same yesterday, today, and tomorrow. Place your trust in Him today and forever.
