"All is the resurrection of the dead. It is sown in dishonor, it is raised in glory . . . [and] raised in power" (1Co 15:42). The "power is . . . strength, which He exerted in Christ when He raised Him from the dead" (Eph 1:19,20). Christ acknowledged he had "'accomplished the work'" (Jn 17:4) and now "upholds all things by the word of His power" (Heb 1:3). "Christ is the power of God" (1Co 1:24). The "kingdom of God does not consist of words but in power" (4:20)). Christ "is able to do far more abundantly beyond all that we ask or think, according to the power that works in us" (Eph 3:20). His primary purpose was to redeem and reconcile mankind to himself. "To us who are being saved [the cross] is the power of God" (1Co 1:18) and the gospel "is the power of God for salvation to everyone who believes" (Ro 1:16). Plus we are "protected by the power of God through faith for a salvation" (1Pe 1:5). Paul said it was a "gift of God's grace which was given to me according to the working of His power" (Eph 3:7). Furthermore "our gospel did not come to you in word only, but also in power and in the Holy Spirit with full conviction" (1Th 1:5).
There is a long term aspect of the "working of His power" (Eph 3:7) "that works within us" (:20). God "will transform the body of our humble state into conformity with the body of His glory, by the exertion of the power that He has even to subject all things to Himself" (Php 3:21). It involves "a salvation ready to be revealed in the last time" (1Pe 1:5) havng "made known to you the power and coming of our Lord Jesus Christ" (2Pe 1:16). Without salvation a person would be "away from the presence of the Lord and from the glory of His power" (2Th 1:9). We are to "be sincere and blameless until the day of Christ" (Php 1:10). Paul's desire was to "confirm you to the end" (1Co 1:8) and he was "convinced that He is able to guard what I have entrusted to Him until that day" (2Ti 1:12).
