I'm reading a book entitled "The Christian Atheist: Believing in God but Living As If He Doesn't Exist," which addresses this question. I believe that a genuine Christian must have a personal relationship with Jesus Christ and reflect that in their daily lives. The 1833 New Hampshire Baptist Confession which is really the bedrock of the Baptist faith states that:
We believe that such only are real believers as endure unto the end;
[2119] that their persevering attachment to Christ is the grand mark which distinguishes them from superficial professors;
[2120] that a special Providence watches over their welfare;
[2121] and they are kept by the power of God through faith unto salvation.
[2122]
The 1925 Baptist Faith and Message states the same thin:
All real believers endure to the end. Their continuance in well-doing is the mark which distinguishes them from mere professors. A special Providence cares for them, and they are kept by the power of God through faith unto salvation.
John 10:28-29; 2 Tim. 2:19; 1 John 2:19; 1 Cor. 11:32; Rom. 8:30; 9:11,16; Rom. 5:9-10; Matt. 26:70-75.
The 1963 Baptist Faith and Message and later ones removed this very significant statement led by Herschel Hobbs, thje chairman of the 1963 statement ushered in the period of "easy believerism" for the SBC.
