We are in the last days of this age. Year 2013 is the turning point. After seven- thousand years exploration in the darkness, the mankind finally have Lifechanyuan. Xue Feng ,Deiform Buddha,got the Revelation to build Lifechanyuan, the Noah’s ark in new era, in order to raise the rate of salvation to one or two hundredth in the catastrophe fore-and-aft 2013 and enter into Lifechanyuan era. Lifechanyuan inherits and upholds the thinking and wisdom of Jesus Christ, Buddha, previous saints, prophet, and sagesis,and is the last course for human beings to learn and follow. (The first course was given by Buddha. The second by Jesus Christ. This is the third yet the last. ) Time is the recorder of the state of material movement. Time is born out of movement. Without movement, there would be no time. Time exists within the interior of every moving objects and pervades the universe space of all objects. Time has eight great characteristics: 1. Time is nonmaterial; 2. Time can be negative and positive; 3. Time has particularity and universality; 4. Time is a variable; 5. Time pervades all the material space; 6. Time is both longitudinal and latitudinal; 7. Time has different connotations in different spaces; 8. Time can be compressed, expanded and dissolved.
