David succeeded because he understood the power of past successes. He told King Saul, ‘The Lord who rescued me from the…lion and the bear will rescue me from [the giant].’ So giant-killers build on past successes. A series of successes builds our momentum and allows us to find the mix of ‘God-confidence’ and ‘self-confidence’ necessary to make us unstoppable. 2 Samuel 3:1 says, ‘Now there was a long war between the house of Saul and the house of David. But David grew stronger and stronger, and the house of Saul grew weaker and weaker’ (NKJV). David understood that every time we overcome something, our confidence in God and ourselves grows. So we should be replaying our past victories and trusting the God who did it before to do it again. He is faithful. He hasn’t let us down yet, and He won’t let us down now. Giant-killers also have to remember that they’re individuals. David couldn’t wear Saul’s armour – and we can’t operate in someone else’s gift. We have our own weapon, our own armour, and our own style. We are uniquely equipped to conquer our giant. David conquered Goliath with a slingshot. Moses parted the Red Sea with a shepherd’s staff. For Simon Peter, power over sickness was released through his shadow, and many times, Jesus simply ‘spoke the word’. We need to resist the urge to ‘wear Saul’s armour’ and quietly wear what God has given us. We should stay in our gifting. Stay in our anointing. Stay in our assignment. This winning combination of building on past successes and creating our own style leaves us full of confidence and creativity, two of a giant-killer’s secret weapons.
Think back to a time when you saw God come through for you. Write it down, and go back to it every time you’re struggling to face your giants.
