Not true. God made us individually, and not one person is the same as another. Besides common foundational biological attributes, every person is dramatically unique, superior in some ways and inferior in others.
I will praise thee; for I am fearfully and wonderfully made: marvellous are thy works; and that my soul knoweth right well. Psalm 139:14
Health, intelligence, common sense, character, attitudes, motives, wisdom, capabilities, personality, appearance, drive, work ethic, prosperity, education, resources, longevity, lineage, and the lot drawn in life are all differentiators between any two of us.
But there is a common thread of equality that runs through every person. We are all guilty of inevitable sin, each deserving of the coming wrath of God. All will be held accountable, and every man will be judged for what he has done in his life. This is the only way in which men are equal.
As it is written, There is none righteous, no, not one. Romans 3:10 For all have sinned, and come short of the glory of God; Romans 3:23 The wages of sin is death . . . Romans 6:23
Thankfully, there is equal opportunity for everyone to turn to Jesus Christ and be reconciled to God. By God’s unmerited favor, we have been offered the gift of salvation. The wise seize the opportunity; there is no condemnation for those in Christ Jesus. Romans 8:1
. . . but the gift of God is eternal life through Jesus Christ our Lord. Romans 6:23
So, there is no equality among men. There is also no social equity or equality of outcome. There is not meant to be, as the Kingdom of God is a meritocracy.
His lord said unto him, Well done, good and faithful servant; thou hast been faithful over a few things, I will make the ruler over many things: enter thou into the joy of the lord. Matthew 25:23
This is how it is with God and how it should be on earth. Corporate or societal success is found in advancing and rewarding the intelligent, industrious, humble, obedient, and grateful souls who have compassion for the less fortunate. We should strive for equality in opportunity for those willing to sacrifice, but outcomes are the result of effort and the providence of God.
