Every one of us will experience moments of apprehension, and denial or trying to hide from it will do no good. When fear arises, ask yourself the following questions: Where does it come from? (You know it isn't from God.) Has God ever failed me in the past? Does He promise to meet all of my needs? Does He keep His promises?
If we read the Bible, we'll find countless stories of God's faithfulness. For example, Paul lived through hardship, persecution, pain, and all kinds of terrible circumstances. The apostle wrote these well-known words: "God causes all things to work together for good to those who love God, to those who are called according to His purpose" (Rom. 8:28). This testifies to the fact that for those who trust in Him, God turns every difficulty, loss, and separation into something good.
From Abraham to Isaiah to David to Job to Jonah to Paul to John, we see God's constant love and care for His people. His Word is a lamp that will give us clear guidance when circumstances are bleak. It offers the best direction we will ever find. When we meditate upon it, pray over it, grapple with it, and incorporate it into our lives, His light chases away the darkness. The psalms, in particular, are helpful in dealing with fear.
God, the sovereign ruler of this universe, is in control of your life. Don't make the mistake of thinking He isn't, simply because He does not operate according to your will and schedule. If you read your Bible and meditate on it, you will find genuine strength in His promises.
