God's Word is eternal. His Word is truth. What you choose to focus hour thought, faith, and action life on is what you will have. How much time do you spend pondering the circumstances of life versus meditating on God's Word, His truth, for your life? Since God's Word is truth, then any circumstance in your life that is contrary for God's truth, the highest truth possible, must be an untruth. Something that is untruth will be found out in due time. The physical world was created out of the spirit. All things that are opposed to God's best for you can be changed by praying, meditating on, and renewing your mind with God's Word and will for your life.
Pick a scripture promise that is an answer to an undesirable circumstance in your life. For example, if you have a pain or a sickness, pick a healing scripture like 1 Peter 2:24, Jeremiah 30:17, or Psalm 103:2-5. Start by meditating one or all of these scriptures for a few minutes each day. The word meditate from the original Hebrew text means to "ponder and mutter (speak softly but out loud) repeatedly". Read them so they get in your eyes. Say them out loud so they get in your ears. Work up to several minutes per day. The more you focus on them, the more they get into your down into your soul so that when that knee pain strikes the first thing that comes out of your mouth are those Godly promises instead of some explicative that against His Word and will for you.
If you are in Christ Jesus, you have the same power inside of you that raised Jesus from the dead and seated Him at the right hand of the Father. Activate that power by taking the TIME to speak faith-filled words over your life! Hallelujah!
