Something to say:
It will be that if you hearken to My commandments… (11:13).
In this, the second paragraph of the Shema, God promises that we will be blessed with prosperity beyond the bounds of natural law, if we obey His commandments. Why does the Torah use the expression Shema, to hearken? Shouldn’t it have said, “I f you will perform My commandments”? Rabbi Avigdor Miller comments that taking action is not always in a man’s power, whereas listening sincerely, with the intention to do, certainly is. When one decides to listen to God’s commandments, he demonstrates his willingness and his genuine intention to perform them. It is according to the “listening,” the effort to learn, that God measures one’s acceptance of the Torah and therefore provides him with innumerable blessings.
There’s a famous saying “It’s the thought that counts”. So long as we are sincere in wanting to do Hashem’s commandments, then we get credit for it.
