Why is it difficult to obey God’s Word?

If Abraham had relied on his own understanding rather than trusting God (Prov. 3:5-6),

Then he couldn’t offer his beloved precious son Isaac to God as a burnt offering when God tested him (Gen. 22:1-2).

The reason is not only because he loved his son Isaac (22:2) whom God gave to him

when he was 100 years old (21:5) but also if he offered Isaac as the burnt offering then God’s promise

“So shall your descendants be” wouldn’t be fulfilled (15:5).

However, Abraham didn’t rely on his own understanding but trusted God and feared Him (21:12).

Thus, he obeyed God’s word and offered Isaac to God (22:9-10; Heb. 11:17)

without withholding his only son Isaac from God (22:12).
