Rules are usually a good thing. Think about driving without any rules (I've been to Haiti and other countries and seen the results of this...bad news). Did you ever play a game with someone who didn't follow the rules...cheaters aren't that fun to be around. Rules are normally a good thing, as long as the person/establishment making the rules is a moral person.
When you compare the rules of the world with God's rules, there is a large separation. The world says that it's all right to respond in anger if you are mistreated....immorality is all right as long as nobody is physically harmed...it's ok mock/gossip about others as long as most people laugh...drunkenness is fine as long as you have a designated driver...this list could go on for quite a while.
Christ's rules are simple and totally opposite of the ways of the world. I think Paul sums up all of God's rules in one of his letters to the Corinthian church:
1 Corinthians 16:14, "Do everything in love."
His statement is founded in Jesus' statement:
John 13:35, "By this all men will know that you are my disciples, if you love one another."
How are you going to show God's love today, this week, this month? What will you do when you are mistreated? Who's rules will you follow? Jesus' rules are tough to follow, but He doesn't ask us to do anything He hasn't done or experienced Himself.
Love others...represent Christ. Do everything in love. Stay strong.
