“Giants” are the problems, mountains, and obstacles in our lives that result from the brokenness of our world, and which may at first seem unsurmountable. They are also personal to the person. Your giant may not be someone else’s giant, but if it is a big problem to you, then it is your giant. Following God does not mean denying our problems, but recognising that while giants are real, so is our God.
In 1 Samuel 17, we read that Israel faced Goliath for 40 days and while Goliath did not attack immediately, he intimidated and taunted the people of God, causing fear in them and weakening their spirits even before any spear was thrown. When David arrived however, he carried with him a greater weapon: faith in the living God. It was David’s trust in God that led to Israel’s breakthrough and victory.
