(1 Samuel 16:13-23) God chooses to use unlikely people for unlikely tasks in unlikely places. To serve the Lord, we’re not expected simply to muster up adequate inner strength. Rather, God Himself enables us through His Spirit. We see this illustrated in 1 Samuel when the Holy Spirit descended upon David and departed from Saul, radically altering both lives. To do God’s work, cautions Alistair Begg, we need the Spirit’s empowering. His presence is crucial, even as His absence is dreadful.
