I apologize for being so slow getting to your question. We are reorganizing our correspondence in an attempt to do better. Confirmation as a religious ceremony is not taught in the scriptures. Some basic form of the rite appeared in the 4th century after Christ and it involved the laying on of hands or anointing with oil. It was established as one of the seven sacraments of the Roman Catholic Church during the Middle Ages. Some form of it is practiced by Anglicans, Lutherans, and some other Protestant churches. The ceremony is supposed to convey the Holy Spirit to the participant in a renewed or fuller way. As a sacrament, it is considered to be a means that helps bring about salvation.
However, since confirmation is not a biblical practice, it cannot be the means of salvation for anyone. I am not saying that it would impossible for a person to get saved at the time of confirmation--only that the confirmation itself cannot save a person. It is a manmade ceremony added to the practice of many religious groups. How could something added by man be a way of salvation?
Salvation comes when an individual first recognizes that they are personally guilty of sins which, if left unchecked, will send them to hell. Then, they learn that their guilt of sin has been paid for by Christ in His sufferings on the cross. They believe that Jesus Christ died on the cross, was buried, and arose from the dead the third day after His resurrection as taught in the scriptures. Finally, they trust in Christ for their personal salvation in an act where they consciously, willingly, and purposefully choose to look to Him as their Lord and Saviour by calling on His name and seeking His forgiveness for their sins. That person then accepts by faith that God has kept His word and has saved them from their sin.
Though salvation is not simply following a formula, the previous paragraph gives a basic summary of what it is to be saved. It is this act of trusting in the Lord as Saviour that saves a lost soul. No other act--not confirmation, baptism, living a good life, belonging to a church, or keeping the ten commandments--no other act can save a soul from hell.
For the sake of space, I have not included scriptures in this answer. However, there are articles on the site that talk about the way of salvation. Also, if you have further questions about this, please ask. This is the most important thing anyone can take care of in their entire life. "For what shall it profit a man, if he shall gain the whole world, and lose his own soul?" (Mark 8:36).
