Abraham’s near-sacrifice of Isaac can be a highly controversial topic, but let’s explore what is happening here. Abraham trusted that God would keep the promise to make a covenant nation of his descendants through his son Isaac, the promised son of his wife Sarah. If God were faithful to this promise, God couldn’t eliminate Isaac because the covenant couldn’t be fulfilled. Abraham trusted that God would be faithful to the promise, so he went forward with sacrificing him, knowing that Isaac couldn’t be taken forever or God would be a liar and covenant breaker.
