“You will keep him in perfect peace whose mind is stayed on you, because he trusts in you” – Isaiah 26:3
There is a strong correlation between the mind and the heart. Here’s what I mean.
The mind’s contemplations and the heart’s affections are revealed to be interwoven throughout the pages of Scripture.
In this passage in Isaiah, we see that to trust in God involves keeping our minds fixed on God. The one whose mind is stayed on the LORD is shown to be the one whose heart trusts in the LORD, and that trust leads to perfect peace.
The Apostle Paul speaks in a similar fashion in Colossians when he writes,
“Since, then, you have been raised with Christ, set your hearts on things above where Christ is seated at the right hand of God. Set your minds on things above, not on earthly things, for you died, and your life is now hidden with Christ in God” (Col. 3:1-3)
The mind and the heart, then, are inseparable. What we believe in our minds determines how we live in our actions, which flows from what we set our hearts on.
What a promise we have here in Isaiah!
There is a potential for perfect peace
Perfect peace is promised in this passage to those who keep their minds stayed on the LORD, because the keeping of the mind on the LORD is an expression, a sign, an indicator that one’s trust is in the LORD.
How can we grow in trusting God today? – By filling our minds with the truths of God, His sovereignty, His holiness, His wisdom, His power, His immutability, His Omniscience, His Omnipotence, and most importantly His great love for us in Christ.
In keeping our minds stayed, fixed, settled on Who God Is, we will enjoy peace within our souls. Our hearts will trust in Him and we will enjoy the promise of perfect peace.
God, in Christ, IS the pathway to perfect peace.
