Jesus gave himself for ours sins. He continues to rescue us by the hearing of His Word. I think it is partially up to us to keep from falling back to our old ways, through continual study, meditation upon His Word and prayer I beleive it is essential and pertains to all Christians that Paul wrote to Timothy in 2nd Timothy2:15," Study to shew thyself approved unto God, a workman that needeth not to be ashamed, rightly dividing the word of truth".
