So soon as the believer has the witness of the spiritual baptism and has received the baptism with water, he should yield himself willingly to receive the baptism of the shedding of his blood for the name of Christ, if required, and take on him the witness of blood, according to 1 John 5:8: “And there are three that bear witness in earth, the Spirit, the water, and the blood; and these three agree in one.
The believer, in his baptism, is baptized into the body of Christ, the church (1 Corinthians 12:13. 27). And then he puts on Christ and unites himself to him to follow him truly and constantly, and bearing his cross after him. And should the believer be called on to suffer for the name of Christ, and to lay down his life for his name, he should be willing to be baptized with the same baptism of suffering and shedding of blood wherewith his Lord and Master was baptized when he laid down his life to redeem man from death, and this is the allegiance of all the true disciples of Jesus Christ in this world. “ye shall drink indeed of my cup and be baptized with the baptism I am baptized with (Matthew 20:23). “If the world hate you, ye know that it hated me before it hated you. The servant is not greater than his lord, if they have persecuted me, they will also persecute you (John 15:18. 20). “They shall put you out of the synagogues: yea the time cometh that whosoever killeth you will think that he doeth God service (John 16:2).
“Behold, I send you forth as sheep in the midst of wolves: be ye therefore wise as serpents, and harmless as doves” (Matthew 10:16). And verses 22 & 25: “Ye shall be hated of all men for my name’s sake: but he that endureth to the end shall be saved. If they have called the master of the house Beelzebub, how much more shall they call them of his household?” “If any man come to me, and hate not his father, and mother, and wife, and children, and brethren, and sisters, yea, and his own life also, he cannot be my disciple. And whosoever doth not bear his cross, and come after me, cannot be my disciple.” (Luke 14:26-27).
For it is evident that when believers, as members of Christ, will enter heaven with Christ the heavenly bridegroom to the marriage supper of the Lamb, and drink of the new and sweet wine in heaven (which is manifested in John 2:10 and Matthew 26:29), that they must first drink with him the bitter wine of affliction and tribulation, and be baptized with his baptism (Matthew 20:22-23). But the drinking of this cup and being baptized with this baptism must be done and endured for the sake of Jesus Christ and for his name alone.
