Most people are familiar with the Biblical account of David and Goliath, even young Sunday school students. David was a young shepherd boy armed only with a sling and three smooth stones, who answered the challenge of a well armed, giant who was a trained and experienced warier. David didn’t care about Goliath’s strength, because he already knew God’s strength. With God’s help, it only took one stone to bring down that Philistine giant.
Many times in my Christian life, I have faced challenges from Satan that appear to be a giant or a mountain blocking my path. Fortunately, I not only know God’s strength, but the Holy Spirit that now dwells in me is the same spirit that raised Jesus from the dead (see Romans chapter 8) and that is more strength than I have ever needed. When I was younger and healthy, God gave me the strength to defeat the giants and climb over the mountains. Now, in my later years, God goes ahead of me to fight my battles and clear the path for me. He either moves the mountains or leads me safely around them.
My brother or sister in Christ, when the enemy challenges you consider it evidence that you are on the right track in God’s service; otherwise he wouldn’t bother with you. When it happens, concentrate on God’s strength within you and He will never let you down.
