Obedience

Last Sunday service was really powerful.. Dr John Avanzini did not teach about his fav topic - biblical economics. Instead, he teaches one of the most basics in Christian life - obedience to God.
3 teachings which impacted me the most.

1) We have angels who work and help us whenever we need. Bible says at the voice of the Word, we can command the angels to overcome the devil and any obstacles! Angels are like servants who are sent by God to help us!
2) We are made in the image and likeness of God. God has called us to rule as kings and inherit everything that He has!
3) But the most important teaching was that we must obey God and do what He has called us to do! He said something which left a deep mark in our heart - If God has saved us from hell, why cant we just obey Him?

The fear of God just gripped my heart that time.. Indeed, God has saved us from the curse of sin and gave us eternal life to rule and reign with Him. Why can't we just obey and listen to Him for this short life time?
