When I came to Christ I realized all He went through. This convicted me that I believed in God by convenience. I called on God before or during a problem in life--basically using Him.
"If anyone wishes to come after Me, he must deny himself, and take up his cross and follow Me." - Mark 8:34
If our worship does not invade every area of our life, then God is not on the throne of our life. We must trust Him in ALL things! We ought to have a passion for His Word as well as an uncompromising willingness to act. We should long for His presence and obediently follow each and every day - not just during our once a week worship.
He loves you just as He loves me. He gave His life so you can know Him personally and be sure of eternal, abundant life with Him. If you just believe in God by convenience, like I used to, consider committing your life to following Jesus in faith. It's a life you'll never regret. It's a life of ultimate meaning and purpose.
