I'm not a fan of Oral Roberts in any way but to his point....where else will you find out about God if not in His Word??
13These things I have written to you who believe in the name of the Son of God, so that you may know that you have eternal life. 1 John 5:13 NASB
30Therefore many other signs Jesus also performed in the presence of the disciples, which are not written in this book; 31but these have been written so that you may believe that Jesus is the Christ, the Son of God; and that believing you may have life in His name. John 20:30-31 NASB
