Ephesians 2:8&9 (AMP)
"For it is by free grace (God's unmerited favour) that you are saved (delivered from judgement and made partakers of Christ's salvation) through [your] faith. And this [salvation] it's not of yourselves [of your own doing, it came not through your own striving], but it is the gift of God; Not because of works [not the fulfillment of the Law's demands], lest any man should boast. [It is not the result of what anyone can possibly do, so no one can pride himself in it or take glory to himself.]"
I believe the word grace is best understood by this definition. It is the empowering presence of God causing us to be all we need to be and do all we need to do. Grace and righteousness teaching are absolutely essential for our reigning in Christ. The message carries with it potential. By that I mean God's potential in you. Surprisingly this message has provoked some people. I have always been amazed at how many Christians don't feel much about themselves so when righteousness teaching and grace and empowerment are presented to them, it is often perceived to be like a tsunami coming over them. We, in evangelical circles, have long held value systems that all are great in their potential, but have not always been systematically taught in a way that causes progression in the Christian life.
I hope this does not offend you, but someone once said that the greatest waste of potential and energy is the over 60 group who are on the golf courses throughout the world. I do believe the church is like a sleeping giant that needs to be awakened. Acts 1:18 talks about an enduement of power that flows out from the believer. This enduement is like a river changing the course of history and directing the steps of nations. In John 17:15 those of Jesus' day marvelled at the knowledge that he had. They knew he had not gone to their schools yet he taught in a way that caused them to be beside themselves. Jesus preached that we should pray thy will be done on earth as it is in heaven. We are on earth, but we belong to a kingdom from above. In that kingdom, according to 2 Corinthians 5:20, we are called to be ambassadors. The grace, righteousness, and power principle is the culture of the New Testament. It has the ability, according to the book of Acts, to turn the world upside down. Jesus only had 12 disciples and 120 on the day of Pentecost, but by Acts 17:6 they were shaking nations. If that is true then we in the church need to embrace the power of the gospel. Paul said that he was not ashamed of it and he understood and knew that the foolishness of it was the power of God, 1 Corinthians 1:18. This gospel is not entirely rational to some. According to Paul it appears to be foolishness to those in the world yet wherever people who dare to believe it, it becomes the game changer in the hearts of those who embrace it.
