I will confirm my covenant with you and your descendants after you, from generation to generation. This is the everlasting covenant: I will always be your God and the God of your descendants after you. Genesis 17:7 NLT
When God made His covenant with Abraham He was making it with all of us. All of the promises that were given to Abraham were given to us.
A member of a church in which I had recently spoken asked me to come to her home. She was very upset because a neighbor claimed to be a witch and put a curse on her home and family. The lady church member believed in God but was afraid of what this curse might mean. When I got to her home I shared this passage with her. It is a promise God made to Abraham.
The Lord had said to Abram, “Leave your native country, your relatives, and your father’s family, and go to the land that I will show you. I will make you into a great nation. I will bless you and make you famous, and you will be a blessing to others. I will bless those who bless you and curse those who treat you with contempt. All the families on earth will be blessed through you.” Genesis 2:1-3 NLT
The Lord promised to bless those who blessed Abraham and to treat those who cursed him with contempt. I actually think the KJV is a little more powerful on this point when it says, “I will bless them that bless thee, and curse him that curseth thee.” Right after this promise was given, Abraham went into Egypt, and instead of trusting God to care for him, he trusted a lie he invented that Sara was only his sister, not his wife. Not only are lies deceitful, they show we are not trusting God. When we trust God we have no reason to make up lies. Pharaoh took Sara to himself, not knowing she was married. Even though Abraham was less than perfect in this situation the Lord still kept his promise like He always does.
But the Lord sent terrible plagues upon Pharaoh and his household because of Sarai, Abram’s wife. Genesis 12:17 NLT
Even when Abraham was less than perfect and even had trust issues, the Lord kept His promise to curse those who cursed him. I reminded the lady that Balaam tried to curse Israel but could only bless them! See Numbers 23:11-12. The Lord’s blessing continued for the great nation of Israel the Lord had promised to Abraham. The lady thought that was all wonderful for Abraham, but what did that have to do with her and the curse that was placed upon her? I asked her if she belonged to Christ and, of course, she said she did. I told her I had good news for her.
And now that you belong to Christ, you are the true children of Abraham. You are his heirs, and God’s promise to Abraham belongs to you. Galatians 3:29 NLT
The promise to bless those who bless you and curse those who curse you belonged to her just as much it did to Abraham. She claimed this promise, and many months later, the neighbor was gone and there were no signs of any curses.
Once an elder in my area was being slandered by some of the other church leaders. Thank God the church body could see through the other leaders’ lies and stood up for him. When the truth came out, and the elder was exonerated, one of his enemies, who was also a leader, was too proud to recant his lies and accusations. Not long after, the leader who made the false accusations retired to a new area. Soon he had to move far away from the area in which he retired, because of accusations made against him which were much more serious than the one he made against the local elder. Some called it karma, some called it “what goes around comes around.” But I can’t help but think of God’s promise, “I will bless those who bless you and curse those who curse you.” I hope, too, that this situation led the slandering leader to repentance and salvation.
Now before we start acting all high and mighty when God works in our favor, it’s important to remember that God blessed Abraham because of His own faithfulness, not the faithfulness of Abraham. Even though God cursed Pharaoh, Abraham still had his own lesson to learn about honesty and trusting God instead of lies. I would imagine even when God curses those who curse us, we still need to humbly learn some lessons as well. The promise in Genesis 12:3 goes on to say that all families of the earth will be blessed, as God wants to bless and save all of us – friends and foes, just as he saved faulty Abraham.
