This world is the place of sacrifice. We all came here to make sacrifices. We wanted to come here, we knew it would require sacrifice to produce the faith necessary for salvation, and we gladly came.
Christ is the great Prototype of the “saved man” according to the Lectures on Faith. He came and gave Himself as a sacrifice, and we are to “follow Him” if we are to be saved.
We came here to lay on the altar everything, our desires, appetites, passions, and everything with which the Lord has blessed us. Abraham put his beloved son on the altar, intending to kill him and then burn his remains, because God asked it of him. He did not refuse. However bitter, terrible and painful the request, the Lord asked it of Abraham and he proceeded to offer it.
No one obtains the faith necessary for salvation unless they are prepared to sacrifice all things to God. Faith for salvation cannot otherwise be obtained. Read the Lectures on Faith again. You’ll see it is all set out there.
