“In due course” is an English way of encouraging patience. The six months between signing a book contract and holding the printed book in your hand is something akin to the old Chinese water torture: drip. But Patience — personalized as a woman — “has her perfect work”. Patience brings perfection.
Revelation 9:15 speaks of four bound angels (demons it would seem, from the description) who’ve been restrained “for the (definite article in NT Greek) hour, and day, and month, and year.” There’s wisdom in this for apostolic and evangelistic ministries. “Cometh the hour, cometh the man,” as the old saying has it. But not always the moment and rarely consciously beforehand.
We might know when we are in the year, and maybe the month, and even the day. The gift of the tribe of Issachar was understanding the times and knowing what ought to be done during them. We can know the times and the seasons, but not the hour of Christ’s return — Jesus said so; the time God’s sole prerogative.
Likewise, may know when a season is coming for a series of meetings but only the Lord knows when the right time has come for them to begin. The Lord’s time later proves to have been perfect.
Evangelist Oral Roberts never undertook a new project before hearing from God. If you have been fretting while waiting, stop, because it will not hurry things up one bit. The Lord once said to me: “You are impatient to the degree that you believe I am late.” My response was: “But Lord, you are never late!” No reply. None needed. Lesson learned.
