The true children of God, the sons of God they are taught by God because those who who are being led by the Spirit of God, they are the children of God. You can only learn from God if you have the Spirit of God, if you are led by the Holy Spirit, Jesus Christ in you.
You cannot get to know God by reading about Him in the Bible or hearing about Him from other people. You learn the ways of God through your relationship with Him. If you have no relationship with Jesus, then you will never get to know Him and that is why He will say to most believers:”Go away I never knew you.” They had no real relationship with Him. They did not walk with Him, they did not follow Him, they were not guided by the Holy Spirit, so they were never taught by Him. Are you being led by the Spirit of God and are you being taught by God?
May Jesus bless you.
