1. To display His power
As he went along, he saw a man blind from birth. His disciples asked him: “Rabbi, who sinned, this man or his parents, that he was born blind?’
“Neither this man nor his parents sinned”, said Jesus, “but this happened so that the works of God might be displayed in him.”
“What then shall we say? Is God unjust? Not at all!” For he says to Moses, “I will have mercy on whom I have mercy, and I will have compassion on whom I have compassion.”
It does not, therefore, depend on human desire or effort, but on God’s mercy. For Scripture says to Pharaoh: “I raised you up for this very purpose, that I might display my power in you and that my name might be proclaimed in all the earth.” Therefore God has mercy on whom he wants to have mercy and he hardens whom he wants to harden.
2. Because I am not ready to possess
But I will not drive them out in a single year, because the land would become desolate and the wild animals too numerous for you.
3. Because He knows what I can handle
‘When Pharaoh let the people go, God did not lead them on the road through the Philistine country, though that was shorter. For God said, “If they face war, they might change their minds and return to Egypt.”
4. Because God is timing His vengeance
‘In the fourth generation your descendants will come back here, for the sin of the Amorites has not yet reached its full measure.’
‘I will harden the hearts of the Egyptians so that they will go in after them. And I will gain glory through Pharaoh and all his army, through his chariots and his horsemen. The Egyptians will know that I am the Lord when I gain glory through Pharaoh, his chariots and his horsemen.’
5. Because He wants us to step into the authority He has given us to rule on His behalf
‘He got up, rebuked the wind and said to the waves, ‘Quiet! Be still!’ Then the wind died down and it was completely calm.
He said to his disciples, ‘Why are you so afraid? Do you still have no faith?’
‘Then the Lord said to Moses, ‘Why are you crying out to me? Tell the Israelites to move on. Raise your staff and stretch out your hand over the sea to divide the water so that the Israelites can go through the sea on dry ground.’
6. Darkness does not always mean absence of His presence
It may be dark because I am in the shadow of his wing.
‘He will cover you with his feathers, and under his wings you will find refuge; his faithfulness will be your shield and rampart.’
‘Keep me as the apple of your eye; hide me in the shadow of your wings.’
