Answer: God puts us INTO Christ at baptism, (verse 27). The baptism INTO Christ is a result of our faith IN Christ Jesus, (verse 26). ACTION always accompanies the belief.
MORE INFORMATION AND/OR OTHER SCRIPTURE REFERENCES:
Putting on Christ in baptism is being put INTO Christ also. Those who are clothed with Christ, having PUT ON Christ, and who are now also IN Christ must also PUT ON the proper armor of a child of God--a son of God, a soldier of Christ and God--so that we are properly "clothed" IN Christ and WITH Christ to do battle against our enemy, Satan:
Ephesians 6:10-18: "Finally, be strong IN the Lord and IN His mighty power. PUT ON the full armor of God so that you can take your stand against the devil's schemes. For our struggle is not against flesh and blood, but against the rulers, against the authorities, against the powers of this dark world and against the spiritual forces of evil in the heavenly realms. Therefore PUT ON the full armor of God, so that when the day of evil comes, you may be able to stand your ground, and after you have done everything, to stand. Stand firm then, with the belt of Truth buckled around your waist, with the breastplate of righteousness in place, and with your feet fitted with the readiness that comes from the Gospel of peace. In addition to all this, TAKE UP the shield of faith, with which you can extinguish all the flaming arrows of the evil one. TAKE the helmet of salvation and the sword of the Spirit, which is the Word of God. And pray IN the Spirit on all occasions with all kinds of prayers and requests. With this in mind, be alert and always keep on praying for all the saints."
