The idea of common grace would be illustrated well with Joseph and the home where he was employed.

From then on, because of Joseph the Lord blessed the household of the Egyptian and everything that he had in his house and in his fields. – Genesis 39:5 GNT

What it may illustrate is that there is some measure of consequence that comes to those who do keep God’s law which has an outward appearance such as prosperity. I believe God does work this way. I believe that would be the reason Potiphar’s house was blessed because of Joseph. I believe it is also the reason I am called to pray for those in authority over me and to pray specifically that they may observe the law of God in me.

However, there is more.

When they joined the rest of the disciples, they saw a large crowd around them and some teachers of the Law arguing with them. When the people saw Jesus, they were greatly surprised, and ran to him and greeted him. Jesus asked his disciples, “What are you arguing with them about?”

A man in the crowd answered, “Teacher, I brought my son to you, because he has an evil spirit in him and cannot talk. Whenever the spirit attacks him, it throws him to the ground, and he foams at the mouth, grits his teeth, and becomes stiff all over. I asked your disciples to drive the spirit out, but they could not.”

Jesus said to them, “How unbelieving you people are! How long must I stay with you? How long do I have to put up with you? Bring the boy to me!” They brought him to Jesus.

As soon as the spirit saw Jesus, it threw the boy into a fit, so that he fell on the ground and rolled around, foaming at the mouth. “How long has he been like this?” Jesus asked the father.

“Ever since he was a child,” he replied. “Many times the evil spirit has tried to kill him by throwing him in the fire and into water. Have pity on us and help us, if you possibly can!”

“Yes,” said Jesus, “if you yourself can! Everything is possible for the person who has faith.”

The father at once cried out, “I do have faith, but not enough. Help me have more!”

Jesus noticed that the crowd was closing in on them, so he gave a command to the evil spirit. “Deaf and dumb spirit,” he said, “I order you to come out of the boy and never go into him again!”

The spirit screamed, threw the boy into a bad fit, and came out. The boy looked like a corpse, and everyone said, “He is dead!” But Jesus took the boy by the hand and helped him rise, and he stood up.

After Jesus had gone indoors, his disciples asked him privately, “Why couldn’t we drive the spirit out?”

“Only prayer can drive this kind out,” answered Jesus; “nothing else can.” – Mark 9:14-29 GNT

Simone Weil, a French-born Jewish philosopher, died aged 34 in 1943. During her final illness, someone said to her, “I can only pray for you.” Simone answered, “Why do you say, ‘only’. That’s the best thing you can do for me.”

I am speaking the truth; I belong to Christ and I do not lie. My conscience, ruled by the Holy Spirit, also assures me that I am not lying  when I say how great is my sorrow, how endless the pain in my heart for my people, my own flesh and blood! For their sake I could wish that I myself were under God’s curse and separated from Christ. They are God’s people; he made them his children and revealed his glory to them; he made his covenants^[a] with them and gave them the Law; they have the true worship; they have received God’s promises; they are descended from the famous Hebrew ancestors; and Christ, as a human being, belongs to their race. May God, who rules over all, be praised forever!^[b] Amen. – Romans 9:1-5 GNT

Sound like he had a bit of what Esther had. I know God is talking to me about this. It takes more than common grace.

C. H. Spurgeon (Metropolitan Tabernacle Pulpit [Pilgrim Publications], 24:410-411) reported how John Bunyan said “that he often felt while preaching that he could give his own salvation for the salvation of his hearers.” Then Spurgeon stuck the knife in: “And I pity the man who has not felt the same.”

I need to pray much more, need to give my heart to the lost far more than I do now. Lot’s of room to grow past common grace.

God is pleased sometimes to answer the prayers of unbelievers. Indeed he hears not their prayers for their goodness or acceptableness, or because of any true respect to him manifested in them, for there is none. Nor has he obliged himself to answer such prayers. Yet he is pleased sometimes, of his sovereign mercy, to pity wicked men, and hear their cries. Thus he heard the cries of the Ninevites (Jonah 3) and the prayer of Ahab, 1 Kin. 21:27, 28. Though there be no regard to God in their prayers yet he, of his infinite grace, is pleased to have respect to their desires of their own happiness, and to grant their requests. He may, and sometimes does, hear the cries of wicked men, as he hears the hungry ravens when they cry, Psa. 147:9. And as he opens his bountiful hand and satisfies the desires of every living thing, Psa. 145:16. Besides the prayers of sinners, though they have no goodness in them, yet are made a means of a preparation for mercy. – Jonathan Edwards
