A strong conviction: Discipline

Without discipline you will:

-have weak and unreliable faith
-have a poor and up-and-down testimony
-have life of minimal service for God
-have a weak prayer life
-be much more prone to debilitating defaults
-have poor work ethic

With discipline you will:

-be able to walk with God and not forsake prayer to the excuse of not feeling like it
-be able to learn and study and grow
-be able to do things when you don't feel like it
-be responsible to others, and keep your word
-have more potential to break free from life-killers, like wrong assumptions and bad habits
