What shall we do to be saved? The simple and clear answer is found in Acts 22:16 KJV,
And now why tarriest thou? arise, and be baptized, and wash away thy sins, calling on the name of the Lord.
Now there are crusades that claim to have saved millions. They usually practice unscriptural methods of salvation such as asking for a decision card or a prayer of salvation. Why don’t they start others off with a firm foundation? It is because they don’t know the Truth themselves. This leaves another glaring question. How many of those souls never found the narrow gate because they were never washed of their sins, because they weren’t invited into the family of God at the point of conversion?
The start often determines the finish. All of the major crusades whether in California or Africa should not only preach baptism from the start they should practice it. I found that a large crusade in California hosts baptism on the beach a few weeks after the conference. How many souls are lost between the crusade and the baptisms?
I’m not saying decision cards aren’t a good way to connect you to a local Church and I’m not saying a prayer of salvation can’t be the beginning of a relationship with Christ. What I am saying is that the correct knowledge of the Gospel includes baptism for the remission of sins into the body and family of Christ. It is crucial.
Jesus said, in Matthew 28:19-20 KJV, Go ye therefore, and teach all nations, baptizing them in the name of the Father, and of the Son, and of the Holy Ghost:  Teaching them to observe all things whatsoever I have commanded you: and, lo, I am with you alway, even unto the end of the world. Amen.
