The Greatest Commandment | Mark 12:28–34
Since Mark 11:27, Jesus has been accosted by questions in
the temple. One now comes from a scribe,
an expert in the Law of Moses. He was one
from the Pharisees, meaning he would have been pleased with Jesus’s response to
the Sadducees, but he came to Jesus to test Him (cf. Mt 22:34–35). Setting aside this scribe’s motives for now,
this question grants us an invaluable lesson on righteous living, which we will
examine today and tomorrow.
The greatest commandment is knowing God. In vv. 29–30, Jesus quotes from Deuteronomy 6:4–5,
a passage known as the Shema (Hebrew for “hear”). This important passage became a creed devout
Jews recited every morning and evening.
The command starts by defining Who He is. First, a believer must see Him with the
possessive—“The Lord our God”—not just the God of the Bible or of the
forefathers. Second, a believer must
understand that He “is one Lord”—meaning unique, for “there is no one
else besides Him” (v. 32). This can only
explain the Triune God of Scripture—three persons but one God, extending unity
to us who believe.
The greatest commandment is also loving God. Notice that this is a verb—love isn’t a
feeling but an action. The command to
love God is so important that God repeats it two more times in Deuteronomy
(10:12–13; 30:6).
Jesus enumerates the ways in which we are to love in v. 30,
which includes all your heart, soul, mind, and strength. The heart represents the inner man, his
thoughts and emotions, and it can defile a person (Mk 7:15). The soul distinguishes individuals, but it
can be lost to Hell (8:35–36). The mind
obviously focuses on a person’s thoughts, and it can be full of lusts and
darkened in understanding (Eph 2:3; 4:18).
Everything must be changed with all our power, so the command to love
affects every part of a person. Where we
find we fall short, we must repent, believe in the gospel, and live the life He
commands.
