What is the church? And what can we liken it to in Genesis 22 still?
"And he said, “Take your son,
your only child, Isaac, whom you love, and go to the land of Moriah,
and offer him there as a burnt offering on one of the mountains where I will tell you.” And
Abraham rose up early in the morning and saddled his donkey. And he
took two of his servants with him, and Isaac his son. And he chopped
wood for a burnt offering. And he got up and went to the place which God
had told him. On the third day Abraham lifted up his eyes..."
Those whom God calls and those who hear and obey and suffer for it and serve when and where and how they are called, will be a testimony to Christ. Their very lives, their very suffering will point to the suffering of Christ! This makes perfect sense. The church are those given the Holy Spirit and the Holy Spirit is always testifying about Christ. How could we not? Abraham's call to sacrifice. Isaac's call to be the sacrifice. Three days of thinking Isaac as good as dead. Abraham is being invited to know God in ways we could never know him just by reading about him.
"If anyone serves me,
he must follow me, and where I am, there my servant will be also. If
anyone serves me, the Father will honor him.” John 12
The church are those who's suffering, who's prosperity, who's very lives are a living testimony to Jesus Christ who's life, death and resurrection are a testimony to the Father.
