Since ho humans are perfect we are all in need of God's mercy.
What does may God have mercy mean?
This is a quality that has to do with
compassion, forgiveness, and leniency. If convicted of a crime, you might plead for the judge's mercy, meaning a lesser punishment. When people say "May God have mercy on me!" they're asking for forgiveness. Mercy may be given or received.
God's grace is
God's unmerited favor and love toward humankind. It is an unconditional act of his kindness and mercy...
God's grace is an attitude of God towards humans and it does not interfere with any of the lessons we are learning in this life.
No, God's grace is extended to for everyone, it is not only for followers of religions.
Justice is not payback, justice is punishment when punishment is deserved.
Punishment is the imposition of a penalty for the committed offense.
Payback is an act of revenge or
retaliation for the committed offense.
“In His Tablets ‘Abdu’l-Bahá explains the difference between revenge and punishment. He affirms that individuals do not have the right to take revenge, that revenge is despised in the eyes of God, and that the motive for punishment is not vengeance, but the imposition of a penalty for the committed offence. In Some Answered Questions, He confirms that it is the right of society to impose punishments on criminals for the purpose of protecting its members and defending its existence.”
The Kitáb-i-Aqdas, p. 203
The Messengers of God are the Manifestations of universal Prophethood Who appeared independently. They are the lawgivers and the founders of a new cycle of religion, by which the foundations of new religion are established, and a new book is revealed. The Manifestations of universal Prophethood Who appeared independently are, for example, Abraham, Moses, Christ, Muhammad, the Báb and Bahá’u’lláh, but there were others.
Question.—How many kinds of Prophets are there?
Answer.—Universally, the Prophets are of two kinds. One are the independent Prophets Who are followed; the other kind are not independent and are themselves followers.
The independent Prophets are the lawgivers and the founders of a new cycle. Through Their appearance the world puts on a new garment, the foundations of religion are established, and a new book is revealed. Without an intermediary They receive bounty from the Reality of the Divinity, and Their illumination is an essential illumination. They are like the sun which is luminous in itself: the light is its essential necessity; it does not receive light from any other star. These Dawning-places of the morn of Unity are the sources of bounty and the mirrors of the Essence of Reality.
The other Prophets are followers and promoters, for they are branches and not independent; they receive the bounty of the independent Prophets, and they profit by the light of the Guidance of the universal Prophets. They are like the moon, which is not luminous and radiant in itself, but receives its light from the sun.
The Manifestations of universal Prophethood Who appeared independently are, for example, Abraham, Moses, Christ, Muhammad, the Báb and Bahá’u’lláh. But the others who are followers and promoters are like Solomon, David, Isaiah, Jeremiah and Ezekiel. For the independent Prophets are founders; They establish a new religion and make new creatures of men; They change the general morals, promote new customs and rules, renew the cycle and the Law. Their appearance is like the season of spring, which arrays all earthly beings in a new garment, and gives them a new life.
With regard to the second sort of Prophets who are followers, these also promote the Law of God, make known the Religion of God, and proclaim His word. Of themselves they have no power and might, except what they receive from the independent Prophets.
