The language, again, of Ananias about baptism sounds strange in some ears, and yet the experience of missionaries is a sufficient explanation of it. What is that language? "Arise, and be baptized, and wash away thy sins." These words sound startling to one accustomed to identify the washing away of sin with the exercise of faith, and yet there they stand, and no method of exegesis will avail to make them say anything else than this, that baptism was for Saul the washing away of sin, so that if he did not accept baptism his sins would not have been washed away. The experience, however, of those who labour in the mission field explains the whole difficulty. Baptism is the act of open confession and acknowledgment of Christ. St. Paul himself teaches the absolute importance of this confession: "With the heart man believeth unto righteousness; with the mouth confession is made unto salvation."[54] Pagan converts are even still abundantly found who are willing to accept the pure morality and the sublime teaching of Christianity, who are willing to believe and see in Jesus Christ the supreme revelation of God made to the human race, but who are not willing to incur loss and persecution and trial for His sake by the reception of Christian baptism and a public confession of their faith. They may believe with the heart in the revelation of righteousness and may lead moral lives in consequence, but they are not willing to make public confession leading them into a state of salvation. They are, in fact, in the position of Saul of Tarsus as he prayed in the house of Judas, but they will go no farther. They will not act as he did, they will not take the decisive step, they will not arise and be baptized and wash away their sins, calling on the name of Jesus Christ. And if Saul of Tarsus had been like them and had acted as they do, he might have received the vision and have been convinced of the truth of Jesus Christ and of His mission, but yet his moral cowardice would have spoilt the whole, and Saul would have remained in his sins, unpardoned, unaccepted, reprobate from Christ, because he remained unbaptized. Christianity, in fact, is a covenant, and forgiveness of sins is one of the blessings attached to this covenant. Until men perform its conditions and actually enter into the covenant the blessings of the covenant are not granted. Baptism is the door of entry into the covenant of grace, and till men humbly enter within the door they do not exercise true faith. They may believe intellectually in the truth and reality of Christianity, but, till they take the decisive step and obey Christ's law, they do not possess that true faith of the heart which alone enables them, like Saul of Tarsus, to obey Christ and therefore enter into peace.
