We read in 1 Samuel 17 how David was going to overcome Goliath. He tells Saul he has tackled and killed a bear and lion and was therefore capable of slaying this uncircumcised Philistine. He wasn’t boasting in his own power and strength; he was boasting in the power of the Lord who rescued him.
We all have our own Goliaths. There are two ways to deal with the problem. We can use money, influential contacts, physical strength or guile. But there is only one sure way to prevail against our Goliaths. We need the ‘power of the Lord.’ Of ourselves we haven’t enough ability to overcome the ‘world and the devil.’ As the old chorus says, ‘Go in the strength of the Lord.’
