The Sermon on the Mount was given by Jesus after a short walk from the town of Capernaum to a site above the Sea of Galilee. The sermon begins with a staircase starting from a lowly place and going to a heavenly one. It then gives many illustrations along the path to heaven and then a general procedure for walking along that path and up those stairs. Jesus offers his Golden Rule, and it is a bit different in words from what are usually translated as the Golden Rule, but it is absolutely different in its meaning and power. Observe that each beatitude is an inner state, linked to a response and that they are an upward progression toward a heavenly condition.
Matthew 5 King James Version (KJV)
5 And seeing the multitudes, he went up into a mountain: and when he was set, his disciples came unto him:
2 And he opened his mouth, and taught them, saying,
3 Blessed are the poor in spirit: for theirs is the kingdom of heaven.
4 Blessed are they that mourn: for they shall be comforted.
5 Blessed are the meek: for they shall inherit the earth.
6 Blessed are they which do hunger and thirst after righteousness: for they shall be filled.
7 Blessed are the merciful: for they shall obtain mercy.
8 Blessed are the pure in heart: for they shall see God.
9 Blessed are the peacemakers: for they shall be called the children of God.
10 Blessed are they which are persecuted for righteousness’ sake: for theirs is the kingdom of heaven.
11 Blessed are ye, when men shall revile you, and persecute you, and shall say all manner of evil against you falsely, for my sake.
12 Rejoice, and be exceeding glad: for great is your reward in heaven: for so persecuted they the prophets which were before you.
Matthew 7 King James Version (KJV)
11 If ye then, being evil, know how to give good gifts unto your children, how much more shall your Father which is in heaven give good things to them that ask him?
12 Therefore all things whatsoever ye would that men should do to you, do ye even so to them: for this is the law and the prophets.
13 Enter ye in at the strait gate: for wide is the gate, and broad is the way, that leadeth to destruction, and many there be which go in thereat:
14 Because strait is the gate, and narrow is the way, which leadeth unto life, and few there be that find it.
The Beatitudes are the staircase to heaven, and Jesus’ form of the Golden Rule, which includes the word “should,” creates the thoughts and actions that train your inner-self habits with the abilities needed for the ascent.
The word “should” is often translated as “would” because “would” is easier to understand as it is on everyone’s level and easier to do because it demands little of the person; just be nice to others.
The word “should” challenges you to strive to reach the next level of being.
