40. A weak and somewhat curious disposition may undertake with fervor, being ready to accomplish everything at once; but in the very start it becomes faint and weak, and voluntarily yields. It becomes silent when opposition, disaffection and persecution must be encountered. The fervor that does not persevere in spiritual matters is carnal. Spiritual fervor increases with undertaking and effort. It is the nature of spirit not to know weariness. Spirit grows faint and weary only by idleness. Laboring, it increases in strength. Particularly does it gain in fervor through persecution and opposition. So it perseveres, and accomplishes its projects, even though the gates of hell oppose. "Serving the Lord." (Adapt yourselves to the time.) 41. Some renderings read, "Serve the Lord," for in the Greek "Kairos" and "Kyrios" sound much alike. One means "Time," the other "Lord." I am undecided which is preferable. "Serve the time"--"adapt yourselves to the time"--would be apt. And "Serve the Lord" would not be a bad construction. Let each choose for himself. To serve the Lord means to let all our acts be done as unto the Lord himself, in the effort to serve him, not seeking our own honor, and not neglecting our duty for fear of men or because of their favors; it means to follow the spirit of Nehemiah's declaration when the temple was being built (Neh 2, 20)--We are servants of the God of Heaven. Such was the reply of the Jews to those who attempted to hinder them. Practically, the Jews said: "We do not serve ourselves. Our service is not designed for our own honor, but for the honor of the God of Heaven." I shall, however, adhere to the rendering, "Adapt yourselves to the time." It is equivalent to saying: Direct yourselves according to the time. That is, employ it well; be seasonable, in keeping with Solomon's words (Ec 3, 3-4): "A time to break down, and a time to build up; a time to weep, and a time to laugh," etc. There is a time for everything. The thought is, Exercise your privileges, confining yourself to no particular time; be able to do the duty that presents itself, as Psalm 1, 3 suggests: "He shall be like a tree ... that bringeth forth its fruit in its season." 42. This valuable and excellent doctrine militates against the self-righteous, who confine themselves to set times, to the extent of making the time conform to them and adapt itself to their convenience. They observe particular hours for praying, for eating, for drinking. Should you, in dire need of aid, approach one of them, you might perish before he would disengage himself to assist you.
