When the Creator came to earth as Jesus 2 millenia ago He taught many things about what greatness really is. He, being the greatest person Himself, was in the position to teach us what it means. If we really pay attention to Him and take it to heart, we can also achieve some measure of greatness.
Jesus never taught us to free slaves, instead He taught us to become slaves ourselves. Not to men, but to His Father. It’s sort of like those people that offer their service to a fireman that saves their child from a fire. If we offer our service to Jesus without any desire for recompence, we reserve a reward from His Father in heaven which is far greater than any achievement possible in this life.
Jesus came to save us from the eternal fires of Hell “prepared for the devil and his messengers”, and or, banishment to “outer darkness” with “weaping and the gnashing of teeth”. If we live only to achieve earthly glory and greatness before men (to be first) and live in complete ignorance of the Creator who put us here, we will end up with nothing before our Creator and will be punished with eternal death, regret, shame, etc.
But, if we instead care less about what men think of us. If we acknowledge the truth about our origin. That we are indeed the creation of the true Living God. The One who engineered the universe and designed the earth for us to live on and crafted us and all the creatures that support us here. If we turn from our selfishness and blindness and reach out to His Son, become His willing servants and obey Him out of a pure heart, we can find true meaning and satisfaction in our lives here. We can also invest in a real future Our Creator’s Kingdom!
“…For God so loved the world that He gave His only begotten son. So that anyone who believes in Him should not perish but have eternal life. God didn’t send His Son into the world to condemn the world, but that the world might be saved through Him.” (John 3:16-17)
