The miracle minimizes the need for time.

The miracle is a learning device that lessens the need for time. It establishes an out-of-pattern time interval not under the usual laws of time. In this sense it is timeless. T-1.I.47.

The miracle is the only device at your immediate disposal for controlling time. Only revelation transcends it, having nothing to do with time at all. T-1.I.48. 

The miracle minimizes the need for time. In the longitudinal or horizontal plane the recognition of the equality of the members of the Sonship appears to involve almost endless time. However, the miracle entails a sudden shift from horizontal to vertical perception. This introduces an interval from which the giver and receiver both emerge farther along in time than they would otherwise have been. The miracle thus has the unique property of abolishing time to the extent that it renders the interval of time it spans unnecessary.

There is no relationship between the time a miracle takes and the time it covers. The miracle substitutes for learning that might have taken thousands of years. It does so by the underlying recognition of perfect equality of giver and receiver on which the miracle rests. The miracle shortens time by collapsing it, thus eliminating certain intervals within it. It does this, however, within the larger temporal sequence. T-I.II.6
