“You will keep in perfect peace all who trust in you, all whose thoughts are fixed on you” (Isaiah 26:3, NLT).
“Think about what you are thinking about,” Joyce Meyer teaches. Now that is something to chew on! Instead of obsessing over and analyzing what is wrong in your life or what the enemy throws at you or a promise that you haven't yet received, keep your thoughts focused on the Lord Jesus Christ, and what He has done for you. Dwell on His love that gave His life for you. Dwell on the fact that He loved you enough to take your failures and your sins to the cross so you can be free. Stay in His Word, and learn of His constant presence and abiding promises. Think continually about the strong omnipotent power that God promises for your life, and ask for it. Think constantly about laying your heart before Him, and seeking open heart-felt prayer with Him. Focus your heart and mind and all your attention on the Almighty God who brings you new life. With a steadfast mind and heart, you can know His peace and receive greater faith.
Without faith it is impossible to please God (Hebrews 11:6). Pray for greater faith to believe. Think about having greater faith to believe. Dwell on that thought. Keep it in your mind until it is what you think about continually. Get into the Word and learn that faith comes by hearing and understanding the Word of God (Romans 10:17). Read and pray for wisdom to understand the Word. He does not withhold it from you. He gives it generously (James 1:5). That wisdom helps you discern the author of your thoughts, and offers you God's power to bring your thoughts under His control (2 Corinthians 10:5). He extends the power to you, but by faith you choose to exercise it.
When you exercise your faith, it grows stronger. As you give God the gift of your determined and mustard-seed faith, He gives stronger faith back to you with increasing power to believe. Faith and power must be exercised or they will fade away! Think about the faith He has already given you. Determine to overcome the enemy's lies or your own fearful thoughts, and determine to believe in God's truth that His power is real for you. His power and your faith go hand-in-hand. His power in you grows as you exercise greater faith. Your faith in Him is strengthened by the result of what His power brings. Those who “think about what they are thinking about” and keep their thoughts focused on God's faithfulness and power, shall renew their strength. They shall run and not grow weary. They shall walk and not faint (Isaiah 40:31). They shall know His peace because they will trust in Him.
