One person's time based knowledge and particular level of growth at a given time as a Christian doesn't make them greater than other Christians. No one knew anything when they came through the womb of their mother. And no one knows anything thereafter without the grace of God, in which God's children are commanded to always show to each other.
The Word of God is not a gift for argument centered on human ego and degrees of ability in learning, but a gift of humility and love to express with the humility and love of Jesus.
Jesus is the Spirit of love and humility. To know and apply the Word of God is to know to love with it.
Jesus said in Matthew 18:4 Whosoever therefore shall humble themselves as this little child, the same is greatest in the Kingdom of Heaven.
