Ephesians 4:1-32
3:21 Corresponding to that … now saves you. Peter is teaching that the fact that 8 people were in an ark and went through the whole judgment, and yet were unharmed, is analogous to the Christian’s experience in salvation by being in Christ, the ark of one’s salvation. baptism … through the resurrection of Jesus Christ. Peter is not at all referring to water baptism here, but rather a figurative immersion into union with Christ as an ark of safety from the judgment of God. The resurrection of Christ demonstrates God’s acceptance of Christ’s substitutionary death for the sins of those who believe (Ac 2:30, 31; Ro 1:4). Judgment fell on Christ just as the judgment of the flood waters fell on the ark. The believer who is in Christ is thus in the ark of safety that will sail over the waters of judgment into eternal glory (cf. Ro 6:1–4). not the removal of dirt from the flesh. To be sure he is not misunderstood, Peter clearly says he is not speaking of water baptism. In Noah’s flood, they were kept out of the water while those who went into the water were destroyed. Being in the ark and thus saved from God’s judgment on the world prefigures being in Christ and thus saved from eternal damnation. an appeal to God for a good conscience. The word for “appeal” has the idea of a pledge, agreeing to certain conditions of a covenant (the New Covenant) with God. What saves a person plagued by sin and a guilty conscience is not some external rite, but the agreement with God to get in the ark of safety, the Lord Jesus, by faith in His death and resurrection (cf. Ro 10:9, 10; Heb 9:14; 10:22).
