Matthew 5:19
"Therefore anyone who sets aside one of the least of these commands and teaches others accordingly will be called least in the kingdom of heaven, but whoever practices and teaches these commands will be called great in the kingdom of heaven."
Matthew 11:11
"Truly I tell you, among those born of women there has not risen anyone greater than John the Baptist; yet whoever is least in the kingdom of heaven is greater than he."
If everything and everybody were, by necessity, equal, then it would be impossible to speak of "growing" in grace. We grow because we CAN grow; because God can cause this increase in us; there IS such a thing as greater or lesser grace.
2 Peter 3:18
"But grow in the grace and knowledge of our Lord and Savior Jesus Christ. To him be glory both now and forever! Amen."
You are so correct. He does give more to some than He gives to others. A clear example is found here.
Judges 5:24 Blessed above women shall Jael the wife of Heber the Kenite be,
Those words were also spoken of Noah, Moses, and David.
Mary was only blessed among women.
Luke 1:28 And the angel came in unto her, and said, Hail, thou that art highly favoured, the Lord is with thee: blessed art thou among women.
“In this, I am sure you are mistaken. You seem to think God MUST give out equal measures to everyone. This is untrue, and unBiblical. He gives as He pleases, and it’s all gift, whether big or little. One person may have a capacity for grace like a thimble-ful. Another may have a capacity like an Olympic swimming pool. They might both be filled to capacity, wholly by the gift of God: yet one will be greater than the other.”
And indeed, I know in this that Christ is our righteousness and holiness. Each believer has the righteousness and holiness of Christ.
Differences in gifts, maturity, etc. are normal. Position in Christ, holiness and righteousness are based on no human effort. They are imparted by Christ.
Least, greater, lessor, etc. are positions that do not have anything to do with His imparted righteousness or holiness.
It's got nothing to do with our capacity. It's got everything to do with the God who gives it. WE see each other as being different. I'm sure ants do too. However, compared to God, we have all sinned and are justified freely by His grace.
Acts 10:34-35 So Peter opened his mouth and said: “Truly I understand that God shows no partiality, but in every nation anyone who fears him and does what is right is acceptable to him.
Romans 3:21-26 But now the righteousness of God has been manifested apart from the law, although the Law and the Prophets bear witness to it— the righteousness of God through faith in Jesus Christ for all who believe. For there is no distinction: for all have sinned and fall short of the glory of God, and are justified by his grace as a gift, through the redemption that is in Christ Jesus, whom God put forward as a propitiation by his blood, to be received by faith. This was to show God's righteousness, because in his divine forbearance he had passed over former sins. It was to show his righteousness at the present time, so that he might be just and the justifier of the one who has faith in Jesus.
Ephesians
Ephesians 1:7-10 In him we have redemption through his blood, the forgiveness of our trespasses, according to the riches of his grace, which he lavished upon us, in all wisdom and insight making known to us the mystery of his will, according to his purpose, which he set forth in Christ as a plan for the fullness of time, to unite all things in him, things in heaven and things on earth.
Galatians 3:28 There is neither Jew nor Greek, there is neither slave nor free, there is no male and female, for you are all one in Christ Jesus.
