17:1-58 – David defeats Goliath. This is not only a story about David and Goliath. It is about the Israelites and the Philistines. It is about ‘God’ and the ‘gods’ (43,46). Victory comes from the Lord. It is given by grace. It is received by faith (47). Notice the contrast between the attitude of Saul – unbelief -and the attitude of David – faith (33,37). Unbelief is all around us. Don’t be pulled into it. Don’t forget God. Remember what He has done for you and thank Him that He will not fail you now (37). Put off the armour provided by men. ‘Put on the whole armour of God’ (38-40; Ephesians 6:11). We will not win the victory if we fight in our own strength. We must draw our strength from the Lord. He helps us. We are ‘strengthened with might through His Spirit in the inner man’ (Psalm 121:2; 124:8; Ephesians 3:16).
18:1-30 – ‘Loved’ by ‘all Israel and Judah’ (16,28), David was hated by only one man, the most powerful man in the land – Saul (29). Saul was full of envy (7-8), suspicion (9) and violence (10-11). Saul had been proved wrong (17:33,50), and he didn’t like it! David had more success with the women (7), and Saul wasn’t happy about this! The women shouldn’t have been idolizing David. Saul shouldn’t have been seeking glory for himself. The glory belongs to the Lord – not to David, not to Saul, not to anyone else! ‘Saul was David’s enemy continually’ (29). His real argument was with God. ‘The Lord was with David’ (14,28). This didn’t please Saul – ‘Why am I not getting all this blessing? I’m the king!’. If anyone says, I love God’, and hates his brother, he is a liar… he who loves God should love his brother also’ (1 John 4:20-21).
