To love God with all one’s heart doesn’t leave much room for the world. David, a man after God’s own heart, panted after Him. But it says of Israel, in their backslidden state, that they “...pant after the dust of the earth.” John the Beloved tells us in his first Epistle that a man cannot love God and the world at the same time. Love for God swallows up all other loves, as Moses’ rod swallowed up those of the Egyptians.
When it comes to God and others, two loves cannot co-exist. No matter what, or who, stands in comparison, He must always be the preeminent One. This is why the Lord asked Abraham to offer up his darling son. Isaac held a place in his father’s heart that was on the same plane, and equal to, his love for God. It was good he loved his son, but God tops good!
Worldliness does not have to do so much with dress, amusements, habits, etc. The Bible definition for worldliness is “love not the world”; it has to do with affections. It is not having or enjoying certain things, but rather, setting your affections on them, so that they are loved as much, or above, God.
May God help each of us to love Him so much that, when compared to all else, it will seem like hate. As Leah, who, though dearly loved by her husband, thought she was hated by Jacob because of his greater love for Rachel, may it be so with our love for God.
