Gaining God’s approval involves the proper exercise of our free will. This is because Jehovah does not coerce anyone into serving him. In Isaiah’s time, He asked: “Whom shall I send, and who will go for us?” By recognizing the prophet’s right to decide, Jehovah dignified him. Imagine Isaiah’s satisfaction in responding: “Here I am! Send me.”—Isa. 6:8.
Humans are free to serve God or not to do so. Jehovah wants us to serve him willingly. (Read Joshua 24:15.) Any who begrudge God their worship cannot be pleasing to him; nor does he accept the devotion of those whose true intent is only to please other humans. (Col. 3:22) If we rendered sacred service “hesitantly” by allowing worldly interests to interfere with our worship, we would not win God’s approval. (Ex. 22:29) Jehovah knows that serving him whole-souled is good for us. Moses urged the Israelites to choose life ‘by loving Jehovah their God, by listening to his voice and by sticking to him.’—Deut. 30:19, 20.
King David of ancient Israel sang to Jehovah: “Your people will offer themselves willingly on the day of your military force. In the splendors of holiness, from the womb of the dawn, you have your company of young men just like dewdrops.” (Ps. 110:3) Many people today live for financial security and leisure. For those who love Jehovah, however, their sacred service comes before everything else. The zeal with which they preach the good news proves where their priorities lie. They have full confidence in Jehovah’s ability to supply their daily needs.—Matt. 6:33, 34.
