One of the most common causes of spiritual stultification is fixedness. It is peculiarly common in the realm where Christian truth has been reduced to a fixed form, order, system, and creed. The doctrines of Christianity are such and such; so many. The accepted and established ideas of Christian service and methods are so-and-so. Peter had his fixed position as to Jews and Gentiles, and, because of it, came perilously near missing the larger purpose of God, and presented the Lord with a real battleground in his Christianity. It has so very largely resolved itself into a finality of position, which results in a closed door to fuller revelation as to what God means by His Word. The fact is, that God only gives us enough light to get us to take the next step, but when that step has been taken, we are in the way of being shown that much more was meant by the Lord than He showed then. The first expectations of many servants of the Lord in the Bible, expectations resultant from something said by the Lord to them, were later seen to have been not all that He really meant, but there was something more, and perhaps other than they thought.
Can anyone really dispute that full light very often means a shedding of things and ideas that we thought were of God? Is it not true that, as we go on, we find that certain leadings of the Lord were tactical, intended to get us to a certain place where alone we could learn of a greater necessity? There is very much of this kind of thing in relation to both doctrine, practice, and service—its nature and ways, and while Divine principles will never change to all eternity, the clothing of those principles may vary and change with both dispensations and generations and stages of our own lives.
In all this—while Truth remains unalterable—the only way to grow is to be adjustable and not static and fixed. Do your religious traditions bind you in such a way that you are not free to move with God? If He sees this to be so, He may not give you the light necessary to enlargement. But if He sees that, although you may be in a comparatively false position, your heart is really set on His fullness at any cost, He may present you with light which will test your adjustableness severely. See the case of the disciples of John the Baptist transferring their discipleship to Christ. See the case of Peter and what happened in the home of Cornelius. See also the case of Apollos in Acts 18:24–28, as also the disciples mentioned earlier in that chapter.
