Minding the Mind

October 16, 2026 | David Jeremiah

Who has put wisdom in the mind? Or who has given understanding to the heart?
Job 38:36

Your brain is composed of about 60% fat, floats in cerebrospinal fluid, and weighs about three pounds. It contains 86 billion neurons, consumes 20% of your body’s energy, and operates at speeds of 268 miles per hour.

The most important thing about your brain though is the thoughts that dominate it. The Bible says, “Those who live according to the flesh have their minds set on what the flesh desires; but those who live in accordance with the Spirit have their minds set on what the Spirit desires. The mind governed by the flesh is death, but the mind governed by the Spirit is life and peace” (Romans 8:5-6 NIV).

We must make a conscious effort to fill our mind with Scripture—to read it, study it, and memorize it. We need to meditate on the words of the Bible from Genesis to Revelation. God will keep in perfect peace those whose minds are fixed on Him (see Isaiah 26:3). It is our God who can put wisdom in our minds and understanding in our hearts.

Biblical meditation on Scripture acts as a believer’s medicine because God’s Spirit always uses the balm of His truth to provide lasting comfort and help.
