We are buried with him by baptism into death; that like as Christ was raised up from the dead by the glory of the Father, even so we also should walk in newness of life. Romans 6:4. AG 143.1
Christ made baptism the entrance to His spiritual kingdom. He made this a positive condition with which all must comply who wish to be acknowledged as under the authority of the Father, the Son, and the Holy Ghost. Those who receive the ordinance of baptism thereby make a public declaration that they have renounced the world, and have become members of the royal family, children of the heavenly King.... AG 143.2
Christ enjoins those who receive this ordinance to remember that they are bound by a solemn covenant to live to the Lord. They are to use for Him all their entrusted capabilities, never losing the realization that they bear God's sign of obedience to the Sabbath of the fourth commandment, that they are subjects of Christ's kingdom, partakers of the divine nature. They are to surrender all they have and are to God, employing all their gifts to God's glory. AG 143.3
Those who are baptized in the threefold name of the Father, the Son, and the Holy Ghost, at the very entrance of their Christian life declare publicly that they have accepted the invitation, “Come out from among them, and be ye separate, saith the Lord, and touch not the unclean thing; and I will receive you, and will be a Father unto you, and ye shall be my sons and daughters, saith the Lord Almighty” (2 Corinthians 6:17, 18). “Having therefore these promises, dearly beloved, let us cleanse ourselves from all filthiness of the flesh and spirit, perfecting holiness in the fear of God” (chapter 7:1).... AG 143.4
Let those who received the imprint of God by baptism heed these words, remembering that upon them the Lord has placed His signature, declaring them to be His sons and daughters. The Father, the Son, and the Holy Ghost, powers infinite and omniscient, receive those who truly enter into covenant relation with God. They are present at every baptism, to receive the candidates who have renounced the world and have received Christ into the soul temple. These candidates have entered into the family of God, and their names are inscribed in the Lamb's book of life.47SDA Bible Commentary 6:1075. AG 143.5
