Do we have free will? Yes, as far as natural ability is concerned. No, as far as spiritual ability is concerned (John 3:8-11; 1 Corinthians 2:14). The will is in bondage to sin (Romans 8:8). Only in Christ do we have a will made free. "Therefore, if the Son makes you free, you are free indeed"(John 8:36).
After we are born of the Spirit, through faith in the gospel of Jesus Christ, we are enabled to understand what Scripture teaches. The natural man cannot receive the things of the Spirit of God. After new birth, the Holy Spirit becomes our teacher through Scripture, guiding us into all truth. And, that truth is found in the one who is the truth, Jesus our Lord (John 14:6).
Jonathan Edwards understood that free will from a biblical standpoint must be distinguished between natural ability and spiritual ability. All people have free will as far as natural ability is concerned. That is to say, God has given all of us the ability of choice in the natural world. Yet, people without Jesus Christ are in bondage to sin and unbelief as far as spiritual ability is concerned.
Edwards view of free will was consistent with Scripture, and the teaching of the apostle Paul. The natural man cannot receive the things of the Spirit of God (1 Corinthians 1:18; 2:12-14). He is spiritually dead in sin and trespasses (Ephesians 2:1). His mind is unable to discern and believe what the Holy Spirit teaches (John 3:10-12).
