Salvation was done for us and we weren’t involved in the accomplishment of it, but with salvation, there is a continual process in us. We are saved; Christ has borne our sins; Christ has done all for us; what He did was sufficient and when Jesus said “it is finished” all that needed to be done was finished; and because Jesus lives we have eternal life, however – though we are saved, we are not in place of relaxation or inactivity; our life is still lived out on the earth, in a world full of temptation, continuous trouble, full of sin, we have a physical body/mind, we have an enemy seeking to devour us and so there is a risk, it is necessary enduring and cooperation, there is also a growing, maturing that is required.
