In Isaiah 58 we read God’s view on false worship. Israel sought God daily, “as if they were a nation that did righteousness and did not forsake the judgment of their God”. They fasted, but for the wrong reasons. They humbled themselves, they kept the sabbath, but it was all a facade.
They had the wrong focus. God says “Is not this the fast that I choose: to loose the bonds of wickedness, to undo the straps of the yoke, to let the oppressed go free, and to break every yoke?” Rather than outward shows of serving God, He wanted them to take action in showing His love to those in need. If they did this, then God says “your righteousness shall go before you; the glory of the Lord shall be your rear guard. Then you shall call, and the Lord will answer; you shall cry, and he will say, ‘Here I am.’”
Let’s take God’s advice, “pour yourself out for the hungry and satisfy the desire of the afflicted”. Then “the Lord will guide you continually and satisfy your desire in scorched places and make your bones strong; and you shall be like a watered garden, like a spring of water, whose waters do not fail.”
