God doesn’t owe us an explanation about anything at all.
We answer to Him, not the other way around. Of course, the reality of that can leave us somewhat confused in trying to follow through on His commands. We learn fairly quickly that trusting God doesn’t necessarily mean an easy path.
Moses learns this as soon as he arrives in Egypt, as Pharaoh makes his mission an uphill climb. Nevertheless, the Lord uses every difficulty to demonstrate His power - going to extraordinary lengths to rescue His people. In the same way, God is faithful to rescue us all from the “Pharaohs” that hold us in bondage.
