The first principle of the gospel is faith in the Lord Jesus Christ. Faith means trust--trust in God's will, trust in His way of doing things, and TRUST IN HIS TIMETABLE. We should not try to impose our timetable on His. As Elder Neal A. Maxwell has said:
The issue for us is trusting God enough to trust also His timing. If we can truly believe He has our welfare at heart, may we not let His plans unfold as He thinks best? The same is true with the second coming and with all those matters wherein our faith needs to include faith in the Lord's timing for us personally, not just in His overall plans and purposes. [Even As I Am (Salt Lake City: Deseret Book, 1982), 93]
More recently, during last April conference, Elder Maxwell said: "Since faith in the timing of the Lord may be tried, let us learn to say not only, 'Thy will be done,' but patiently also, 'Thy timing be done'" (CR, April 2001, 76; or "Plow in Hope," Ensign, May 2001, 59).
