Psalm 105:17-19Here is a word for you from the Word.
[God] sent a man before them, Joseph, who was sold as a slave. They afflicted his feet with fetters; he himself was laid in irons, until the time that his word came to pass, the word of the LORD tested him. NAS
The life of Joseph began with great promise. Earlier in his youth, the Lord gave him a dream that showed him that he would be elevated to a position of great authority. He would rule over his brothers. Even his father and mother would come bowing down before him. What happened next? The very opposite of what God had promised. His brothers betrayed him, sold him as a slave into Egypt, and, because he was faithful to his Egyptian master, he eventually ended up in prison. He was in fetters, his soul was in iron.
How did Joseph respond to that situation? Did he say to himself, “Everything’s gone wrong! The Lord’s promise will never come true”? No, I don’t believe that. It says, “Until the time that the promise came, the word of the Lord tested him.” How important it is to see that when the Lord gives us a promise, many times everything that happens next will seem to be the very opposite of what God has promised. It’s so important that at times like that we don’t give up on the promise, we don’t say, “God has forgotten; God has failed.”
You see, that promise that God gave us is testing us. It’s testing our faith and our constancy to see if we’ll hold on in the darkest hour. And when we pass the test, then, like Joseph, the promise will be fulfilled. - Derek Prince
