"You are my strong tower, shelter over me, beautiful and mighty, everlasting King"...and so the song by Kutlass goes. When Child #2 went rock climbing at a nearby gym, I watched as he carefully chose where each hand would grasp a rock. Then, he would pull himself up to the next level, using the strength of his legs to climb higher and then repeat the process. He made it to the top many times, enjoying repelling down to the floor. (I think he's part monkey!)
I look at the walk of a Christian in comparison. We struggle some days to get closer to God...our strong tower. We have obstacles to overcome and strongholds to release (busyness, pride, guilt, fear, etc.) Climbing toward Him means letting go of those rocks that we cling to so desperately. Another child climbing with my son was scared to let go of the rock and stretch out his hand to grab another so he could get closer to the top. He gave up and repelled down. When we trust God in all that we do, it's still scary, but we KNOW He is there with us. He will give us that strength and peace that only He can provide.
"Don't worry about anything; instead, pray about everything. Tell God what you need, and thank him for all he has done.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." Philippians 4:6-7 ( NLT)
