In the thought of faith-based religions such as Christianity and Pure Land Buddhism, we find the logic of the opposition and union of the absolute and the relative. God and man, Buddha and sentient beings, and the absolute and the relative are in opposition to and separate from each other. But that is why, in the religion of faith, they must be united, congruent, and in accord with each other. God descends into the world of man and saves man, and man must repent and return to God. When sentient beings suffer, there must be salvation from the Buddha, and sentient beings afflicted with vexations must be saved by the Buddha.
