Do you know why we shouldn't fear things? Genesis 12-15

Genesis 12:11-13 (NASBStr)

It came about when he came near to Egypt, that he said to Sarai his wife, “See now, I know that you are a beautiful woman; and when the Egyptians see you, they will say, ‘This is his wife ’; and they will kill me, but they will let you live. Please say that you are my sister so that it may go well with me because of you, and that I may live on account of you.”

Perfect love casts out all fear (1 John 4:18).  Actually, the entire verse in John states the following:

1 John 4:18

There is no fear in love; but perfect love casts out fear, because fear involves punishment, and the one who fears is not perfected in love.

The story in Genesis twelve about Abraham and his wife traveling to Egypt is a good example of this put into practice.   Abraham was afraid.  He was afraid that the men of Egypt would see that Sarah was good looking and, as the custom of the land has it, would kill him so they could have her.   We might not be able to relate to this, but that was the way things were done in that day and age.  The reason we might meditate on John's words in a similar situation (where the customs of the land might be dangerous for us) is because it is so practical.   IF we believe that God really loves us, we would not fear any custom in the land.   IF we believe that God loves us we don't have to fear because in His PERFECT LOVE we know that He won't allow anything to hurt us He is not already in control of and want for us.   Even the story of Job is a story of God's love for Job and God's watching over him.   Abraham had been told by God that God would bless him and make his name great.   So, that meant that even though the custom of the land would be to kill Abraham and take Sarah as a prize, God would not allow that to happen.  God had perfect love toward Abraham.   He does to us, as well.  We need not fear.  Fear involves punishment and God won't allow us to be punished.  He might, Himself, discipline us, as any good father does for their children.  But, He won't allow us to be punished.   When we act out of fear we bring torment to our lives.   When we believe God's promises we have joy and peace.   Those are fruits of the Spirit that God produces in our lives.   Fear is not a fruit of the Spirit.
