Before coming to the Lord’s Table for the first time, those who have been baptized and have received confirmation instruction, publicly confess their faith before the congregation, and promise to be faithful members of a congregation that is faithful to God’s Word. After that, the congregation receives them as members eligible to receive Communion, and prays that the Holy Spirit will give them strength to remain in faith in their Lord and Savior until they die, and to inherit eternal life. (The rite of Confirmation).
If young people or adults have not been baptized, before being baptized, they are asked questions similar to those asked in the rite of Confirmation. They are eligible to partake of Communion after being baptized.
Rev. 2:10: Be thou faithful unto death, and I will give thee a crown of life.
Rev. 3:11: Behold, I come quickly. Hold that fast which thou hast, that no man take thy crown.
