And he commanded them to be baptized in the name of the Lord. Then they asked him to stay a few days. (Acts 10:48, NKJV)
The commands of God are not optional. They are necessary because they come from God. Obeying the commands of God expresses our love for God (1 Jno. 5:3). When we obey God’s commandments, we are following the example of Jesus (Heb. 5:8-9). When we obey God’s commands, we submit ourselves to His will as dutiful servants (Lk. 17:10). When we obey Jesus, we trust His word instead of our will (Matt. 14:24-33). We should not view God’s commands and obedience negatively. When Peter commanded Cornelius “to be baptized name of the Lord,” it was because the gospel says believers who are baptized will be saved (Mk. 16:15-16). The Holy Spirit had miraculously testified Cornelius and the others were believers (Acts 10:44-46). Therefore, to forbid baptism to believers (by telling them they are saved before and without obeying God’s command to be baptized) hinders their remission of sins (Acts 10:42-43; 2:37-38; 1 Pet. 3:21). Let us obey the commands of God in faith, trusting God’s will instead of our own.
