It is a glory which shines through Jesus' humble service and death on a cross for sinners. It is a glory of redemptive and suffering love. Transgression literally means to step across a line. God tells us through his word and by our conscience what is right and wrong and what he expects of us. To step across that line is to sin.
Disobedience is related to hearing.
It literally means imperfect hearing , or careless hearing. In the end it means the unwillingness to hear the voice of God. God has spoken to us through his own Son. It is both an awesome privilege to hear the word of God and to be changed by his life-giving word, and an awesome responsibility to believe what God says and to obey it. Lord Jesus Christ, your word is life and truth.
