A warning:
To believe one possesses some volitional will to assent to the truth of the Scriptures despite their clear teachings is to assume one can believe without any initiative by God, that is, one is performing a work to save oneself. But the Scriptures are clear, in that the unsaved:

• is deceitful and desperately sick (Jer. 17:9).
  
• is full of evil (Mark 7:21-23).
  
• loves darkness rather than light (John 3:19).
  
• is unrighteous, does not understand, does not seek for God (Rom. 3:10-12).
  
• is helpless and ungodly (Rom. 5:6).
  
• is dead in his trespasses and sins (Eph. 2:1).
  
• is by nature a child of wrath (Eph. 2:3).
  
• cannot understand spiritual things (1 Cor. 2:14).
  
• is a slave of sin (Rom. 6:16-20).

We are not “born again” as a result of something we have done, but solely on the basis of God’s sovereign will and power.

Soli Deo Gloria!
