Read Exodus 5-9
In Exodus 5 we see the war over the oppressed children of Israel finding deliverance.
The one oppressing them, increases their work, so they have NO TIME for attention to God.
“Make the work harder for the people so that they keep working and pay no attention to lies.” Ex 5:9
The work load causes them to fall into discouragement.
Moses also doesn’t see God at work. He sees things going from bad to worse.
And now the Israelites won’t listen to Moses and his own limitations of speech come to mind. He has shown them signs, he has spoke to Pharaoh but with zero results.
So Moses prays! Great response Moses. Keep going back to the source of the promise! And when he prays he asks his question of the Lord, and God reminds Moses this is all according to my will and plan.
“Then the Lord said to Moses, “Now you will see what I will do to Pharaoh: Because of my mighty hand he will let them go; because of my mighty hand he will drive them out of his country.”
Moses hasn’t seen it yet, but he stays in obedience. Faith stays the course.
