Rather than filling my life with things that make me feel significant, I'd rather fill my life with significant things. Nothing is more significant than the Gospel - the precious, life giving truths of justification by faith in Christ.
God is not punishing you, if you are in Christ Jesus. If you are in Christ Jesus, you have been removed from "first Adam" (oh, how I wish I had more time and space to unpack it!) and God will never punish you. He already poured His wrath out on Christ.
Punishment is just that...punishment. You pay for your sin. Jesus paid it ALL.
Discipline is designed to make you great, girlfriend. It is an indication of His great love for you, and the potential of Christ in you bringing God GREAT glory.
The more you delve into the grace-gospel, the more you better get prepared for greatness. The more you understand the Gospel, the more your life becomes filled with significant things..and the more discipline you will encounter. (Read: "the more you will be held accountable for having right relationships with those in authority in your life, with those who are your peers, and with those under your authority.")
