You are a liar if you say you believe in God, but do not follow his commands. Disciples of Christ are called to follow Gods commands, to obey him. You are only fooling yourself if you just do whatever you want and don’t listen to the Lord. We are called to live through Gods commands and live consistent lives. So if you say you believe, but don’t follow Gods commands then what are you doing? At that point you don’t know God. Your ruining his name. So live through Christ and live in obedience to God. For you will find Joy and God will honor you.
