Isaiah 26:3 tells us that the reason we can keep our minds stayed on Him is because we trust completely in Him. Complete, absolute, unwavering trust in the Lord will cause us to keep our minds stayed on Him no matter what is happening to us. If we are able to do this, we will experience His beautiful perfect peace regardless of the circumstances that we might be faced within our lives.
The Hebrew word that is translated as ‘trusteth’ in Isaiah 26:3 means to “have no fear because of our security.” If we trust deeply in the Lord, we believe that He is completely reliable, that we are absolutely secure, and we have no fear of anything because we know that His power is greater than anything that will ever come against us.
The peace of God will rule in our hearts based upon the amount of His word that lives in our hearts. The key to trusting Him is to have our hearts filled with His word. “Let thine heart retain My words,” Proverbs 4:4. If our lives are controlled by whatever we deeply believe, we should be very careful about what we allow to get deep into our hearts. “Keep thy heart with all diligence; for out of it are the issues of life,” Proverbs 4:23.
Our Father wants us to fill our hearts constantly with His word. When a crisis comes up, He wants His word to be so deeply rooted and firmly established in our hearts that we will automatically react to what His word says instead of reacting with fear to the crisis with which we are faced. “The righteous shall be in everlasting remembrance. He shall not be afraid of evil tidings: his heart is fixed, trusting in the Lord. His heart is established, he shall not be afraid,” Psalm 112:6-8.
We need to have more than just ‘head knowledge’ of God’s word. We need to have ‘heart knowledge’ of His awesome promises. Our hearts need to be so full of His word that it dominates our souls (our minds, our emotions and our will) in times of crisis. If our hearts aren’t filled with God’s word, we’ll falter when the going gets tough. If our hearts are filled with His word, we won’t budge one inch!
Many of us forfeit the peace our Lord has given us by the words that we allow to come out of our mouths when we are under stress. We’ll never enjoy God’s peace unless we learn to control our tongues. Our tongues cannot be permanently controlled by will power. “The human tongue can be tamed by no man,” James 3:8, The Amplified Bible.
Our tongues can only be controlled by what we believe in our hearts. If our hearts are full of worry, fear, doubt and discouragement, then a crisis will bring forth words of worry, fear, doubt and discouragement. Spiritual power is released by the words that we speak. Because of this, we should open our mouths several times each day and speak the word of God. If our hearts are full of the word of God, our lips will constantly speak His word. When our words constantly line up with Gods word, we constantly release His spiritual power.
If we constantly speak Gods word, this will increase our peace. When our ears constantly hear our own lips speaking Gods word, our faith will grow. “Faith cometh by hearing, and hearing by the word of God,” Romans 10:17. It is very important to realize that our faith grows by hearing God’s word. It will grow when we hear other people speak God’s word, but our faith will really grow when our ears constantly hear our mouths speaking the word of God.
As we fill our minds and hearts with God’s word, our faith will become more and more childlike in nature. Little children don’t worry. They trust their fathers completely. Our heavenly Father wants us to face the seemingly complex problems of life with this same innocent, childlike trust in Him.
