This is the second time I've listed First Samuel, Chapter 8 ...but this time I want to approach it from a different perspective.
"He will take your sons, and appoint them for himself, for his chariots, and to be his horsemen; and some will run ahead of his chariots. These sons will reap the King's harvests, and make his instruments of war. And he will take your daughters to be confectionaries, cooks, and bakers. He will take your fields, vineyards, and olive gardens, even the best of them, and give them to his servants ...to serve him. He will take your menservants, and your maidservants, and your goodliest young men ...and put them to work, for him."
If we serve two masters, then we will be so busy we will not be able to give adequate time to the One we should be serving. When we give ourselves to God, we serve Him.
