Read Genesis 22
You gotta have faith.
God commanded Abraham to take his only son out to sacrifice him. God asked him to kill not only a son, but the one who would carry Abraham’s lineage, the one who would receive Abraham’s possessions after his death, his only begotten son.
I know I would have struggled with this command. Knowing how the story ends, and how God rewarded Abraham’s faithfulness by providing a ram to sacrifice instead, I could say I have that much faith, but I know I don’t have the same faith Abraham had.
Faith like that is fleeting these days. Very few are willing to give up comfort, let alone necessities for God. What would you be willing to give up for God? If the answer isn’t everything, you lack the faith of Abraham. I know I am lacking that kind of faith.
“He said, “Do not lay your hand on the boy or do anything to him, for now I know that you fear God, seeing you have not withheld your son, your only son, from me.” – Genesis 22:12
