God tells us that his covenant with us is like the “ordinances” of heaven, the sun, moon, and stars, which have their certain courses, Jer. 31:36. Thence David said that he watched for relief from God “as one watched for the morning,” (Psalm 130:6) a thing that will certainly come in its appointed season. So will be thy relief from Christ. It will come in its season, as the dew and rain upon the parched ground; for faithful is he who hath promised.
