1 Samuel 17:34 But David persisted. “I have been taking care of my father’s sheep,” he said. “When a lion or a bear comes to steal a lamb from the flock, 35 I go after it with a club and take the lamb from its mouth. If the animal turns on me, I catch it by the jaw and club it to death. 36 I have done this to both lions and bears, and I’ll do it to this pagan Philistine, too, for he has defied the armies of the living God!
There’s not a one of us who cannot testify to how God has helped us in the past. Every one of us can recount a time when the Lord has miraculously delivered us. Why then do we doubt that He will do so today? “But this is different”, we might say. “What happened in the past is nothing compared to what I am facing today.” That may be true, but was the miracle God performed in the past all that He can do? Was it the limit of His strength? Couldn’t He have done more?
David believed that the same God that could help him defeat a lion and a bear could also help him to defeat a Philistine giant. “…this uncircumcised Philistine shall be as one of them…”, David declared. To him there was nothing too difficult as long as God was on his side.
Consider Paul’s advice for defeating worry:
Philippians 4:6 Don’t worry about anything; instead, pray about everything. Tell God what you need, and thank him for all he has done. 7 If you do this, you will experience God’s peace, which is far more wonderful than the human mind can understand. His peace will guard your hearts and minds as you live in Christ Jesus.
Tell God exactly what it is that concerns you
Thank Him for everything He has already done
Believe that if He was able to help you so much in the past, surely He will also be able to help you in the future
