Obedience for the sake of self is sin. Many Christians labor to be obedient for the sake of becoming better Christians. They seek obedience knowing that a life of complete obediece would certainly be more fulfilling than their current life of disobedience. They seek obedience out of a quest for a better life for themselves. People will apply scriptural precepts to their own lives for their own benefit. Some Christians will strive for obedience thinking it will give them assurance of life eternal. The problem with this type of obedience is that it is ultimately aimed at pleasing self. We are better off being disobedient in an effort to glorify the Lord, than we are being obedient for the sake of self. Our ultimate concern as Christians must be the glory of God... period. If we are going to be obedient in giving to the church we must be giving for the glory of God, not to ease our conscience, or to receive blessing in return. We resist temptation to bring glory to God, not for fear of punishment. It is all about focus. For too long we have been witnessing because we feel bad for people who are destined for the pits of hell, when we should be witnessing to people because God deserves to be glorified in their life. If we are obedient to the call to witnessing for the betterment of mankind then we are serving man, yet when we witness with the purpose of God being glorified then we are serving the most high. We can all think of our own struggles with disobedience, and if we cut through all the details we will see that the reason we are struggling is because we are seeking obedience in a particular area for our own benefit, if our focus was to glorify God, obedience will simply occur. If our hearts are turned toward the glorification of God, obedience will come naturally.
Well I have to leave, I may continue this later. I haven't proof read this at all so there are probably a million typos.
