When David faced the giant Goliath, this was an impossible problem for him to resolve by himself.
But David knew something about God. God is not someone that will save you using conventional weapons. When God decides to deliver you from some situation, very often He will not do it the way you think. God is always going to do in a way where He will get the glory, and that is why so many people get trapped in impossible situations.
God is bigger than that, so let Him work through you using not conventional weapons. Be open to what God wants to do to you and through you so you can experience deliverance from Him.
