The ways humanity tries to bring about justice, peace, and unity do not and cannot work. History and current events are proof that competing against, controlling, or manipulating others always results in disunity, conflict, injustice, and inequality. Yet competition, force, and manipulation are how humanity has chosen to govern itself. Jesus offers us the sole alternative to humanity’s self-destructive ways: love.
The law of God is this: every last thing you wish others would do to you, do those exact same things to them. This law defines the behavior of perfect love, which is called “charity.” God’s law is the true moral and ethical standard of all humankind, being written into every conscience, and it is the definition of “good.” Behavior that falls short of this law is not good and produces both guilt and conflict with others.
The purpose of the law of God is to end conflict between people. Those who willingly keep His law may joyfully and peacefully live together as equals, both here and now, and forever in the eternal world. The commandments that Jesus gave us in the Sermon on the Mount are how we are to obey the law of God through our works and end our conflicts with others.
Love, the feeling which makes us want to do what the law of God commands, is given to us by God. Charity is Jesus’s nature, meaning He feels perfect love towards everyone. Charity is the nature of all those who inherit God’s kingdom with Jesus. Jesus’s commandments in the Sermon on the Mount are the actions which those who have charity do by nature.
“Sin” is intent or action which falls short of the law of God, such as giving in to lust and doing to others what we do not wish others would do to us. “Repent” means to change one’s mind, to reconsider, or to relent, all of which implies a willing change in one’s behavior.
Any who will believe Jesus’s words in the Sermon on the Mount as literally as small children believe their parents’ words, and repent of all their sins, and be baptized by one of His sent servants, shall be visited by God with fire and with the Holy Ghost and shall receive a remission of their sins.
The visitation of the Holy Ghost changes our feelings so that we understand Jesus’s love and want to only do good. Then we are to do what Jesus commands until the end of our lives. We trust in Jesus to guide and comfort us in our trials and afflictions as we learn who and what He is by the things we suffer in obedience to His teachings. Just as one does not learn a new skill without practice, nobody can understand nor master the discipline of perfect love without doing its works. Doing the works Jesus commanded until we fully understand Him and freely agree to become what He is and to receive His nature from Him permanently as a gift by His grace so that we love everyone perfectly just like He does is what it means to be a disciple of Jesus.
