I believe Jesus’ rebuke towards Martha was justified. It is written that Martha was distracted with much serving. Mary, however, focused her attention towards the Guest Himself, and absorbed all the words and teaching of the Son of God. Jesus rebuked Martha in her busy ways, which kept her from the most important issues. Martha’s sin was in her busyness, an overabundance of serving at the moment. Exceeding in worldly care will unavoidably bring us to spiritual bankruptcy, which will lead to serious consequences. Isaiah 5:12–14 reveals that it will entrap a soul to the enemy, lead to spiritual thirst and hunger, and ultimately the destruction of a soul.
“The harp and the strings, The tambourine and flute, And wine are in their feasts; But they do not regard the work of the LORD, Nor consider the operation of His hands. Therefore my people have gone into captivity, Because they have no knowledge; Their honorable men are famished, And their multitude dried up with thirst. Therefore Sheol has enlarged itself And opened its mouth beyond measure; Their glory and their multitude and their pomp, And he who is jubilant, shall descend into it.” (NKJV)
Let’s take an example from Mary and let’s put the care for our eternal souls and the souls of our children and loved ones as priority. Because it is exactly what will bring blessing: “But seek first the kingdom of God and His righteousness, and all these things shall be added to you. Do not worry about tomorrow, for tomorrow will worry about its own things” (Matthew 5:33, 34a, NKJV). This way neither flesh nor spirit will have any harm.
