"Righteousness" means those who live in a state of caring for others, who believe that it is important to serve and to love the neighbor. To "persecute" means to attack people based on their beliefs. An example of this would be when Jesus himself healed people on the Sabbath and was criticized by the Pharisees (Mark 3:1-6; Luke 6:6-11; Luke 14:1-6). Clearly He was doing what was loving and caring, but was persecuted by the Pharisees because it was not in accord with their beliefs.

And what is the reward for these people? A "kingdom" has reference to a church, and especially to the beliefs that define a church. The kingdom of heaven, then, describes the true ideas that define the Lord's church and guide the lives of angels. So those who seek to serve others, and stick to it even when they are told they are wrong, are actually the most right of all.

1053. That 'and the bow will be in the cloud' means the state of that man is clear from what has been stated and shown already about the bow in the cloud, that is to say, in the next life a person or soul is known among angels from his sphere; and as often as it pleases the Lord that sphere is represented by means of colours like those of the rainbow, variously according to each person's state as to faith in the Lord and thus respectively as to goods and truths of faith. In the next life colours present themselves to view, which on account of their brilliance and splendour are immensely superior in beauty to colours seen with the eyes on earth. Each colour represents something celestial or spiritual.

[2] Those colours derive from the light in heaven, and from the variegation of spiritual light, as stated above. Indeed angels live in light so bright that the light of the world is in comparison no light at all. The light of heaven in which angels live, compared with the light of the world, is as the light of the sun at midday to the light of a candle that is put out and ceases to give any light at all when the sun rises. In heaven there is celestial light and there is spiritual light. Let me compare the two by saying that celestial light is as the light of the sun, while spiritual light is as the light of the moon. But all manner of variation exists depending on the state of the angel receiving the light. The same applies to colours since they are a product of the light. In the heaven of celestial angels the Lord Himself is the Sun, and in the heaven of spiritual angels the Moon. To people who have no conception of the life which souls lead after death these matters are unbelievable. They are nevertheless completely true.
