Why are you so fearful? How is it that you have no faith? (Mark 4:40 NKJV)
Often the fear that we experience in our lives concerning a situation not improving is rooted in placing limitations on God's ability in our mind. Our mental expectations of what God is able to do in our lives is not rooted in His promises or what He has spoken to our hearts, but instead on pondering over the limitations we have experienced in the past, the negativity others have spoken, natural reasoning, or even unconscious self-condemnation on our part. We must receive the promises of God in our heart and make Him THE final authority in our lives!
The manifestation of God's promises are not constrained by how long we have been in a situation for example. In the Bible, there was a woman who had an issue of blood for twelve years that received healing (Matthew 9:20-22) and a lame man that was healed after 38 years of not walking (John 5:5-9). Often when a situation has gone on for a long time, we mistakenly believe the lie that it will never improve. Notice however that as soon as Jesus arrived on the scene and these two people who had been ill for years simply accepted His Healing Word into their hearts (without questioning), they were instantly healed!
The Bible admonishes us to guard our heart with all diligence (Proverbs 4:23). We must be careful not to allow people to speak negative thoughts over us concerning God's promises or rehearse our own past failures in our minds! The manifestation of God's promises are not constrained by people's opinions or what you have experienced up to this point in time but only by His ability which is limitless! Forget what has not worked up until this point (Philippians 3:13) because God is doing a new thing on today (Isaiah 43:19)! In fact, you are not waiting on God because He has already provided everything for you before the foundation of the world (Hebrews 4:3), it is already done! Embrace God's Word in your heart on today and see the manifestation of all He has promised you!
