Yeshua obeyed and taught the Torah. The sermon on the Mount, the only sermon recorded for us, is His teaching of the Torah. It begins with the Beatitudes that sound like a Psalm.
He then goes on to speak of not abandoning the Torah but practicing it and the importance of teaching it. His standards are high, and it is not as if He has a higher standard than His Father. No, He is giving the proper interpretation.
For any commandment that is given by God there is the issue of the heart at its core. Adonai sees the heart, not just the outward appearance or observance. That does not mean that the outward observance is not important. Instead it means that the observance should flow from a heart truly devoted to Him. Out of such a heart the observance of the commandment will be true and pure.
To observe the commandments with an impure heart is sin and to have a pure heart and not actually observe the commandment is also sin. Both are disobedience. It cannot just be interesting information to enlighten our hearts, it must move to observing what has been learned to make a true and complete transformation in the person.
Let us love Him with a pure and clean heart so that we may serve Him through obedience to His commands!
This is what we are to strive for through the power of the Holy Spirit!
