There is no denying that salvation is of the Lord. He is the author of our salvation. He is the finisher of our salvation. It is He who gets all the credit for saving us. Our decision to approach God in humble repentance merits us nothing. Admitting that we are under the curse of sin does not save us. God is not under any obligation whatsoever to save us. He is compassionate. He is merciful. Our decision to repent is not the same as His decision to save us. Calvinists fallaciously equate these two ideas. None of His plans are thwarted because He has given us the ability to either accept or reject Him. Faith is the opposite of works (Romans 11:6). Atonement is available to all. It is applied freely to all who come to Christ by faith. It is God who regenerates us. The gospel itself has sufficient power to draw any sinner to God (Romans 1:16; 1 Corinthians 1:21; Hebrews 4:12). To insist otherwise is nonsense and so reduces its power to nothing. Faith is not meritorious, but the antithesis of works (Ephesians 2:8-9). Christ's substitutionary atonement is not merely an example to follow, but was actually done for the sins of mankind.
The Bible is crystal clear that we must execute a decision to humble ourselves when seeking the forgiveness of God (2 Kings 22:19; 2 Chronicles 12:7; Matthew 18:4; James 4:10; 1 Peter 5:5-6). This is not heresy, but is an emphatic teaching of Scripture. In fact, the Calvinist systematic is loaded with problems of its own. It makes everything a meticulously designed puppet show. It gives the lost a perfect excuse on Judgement Day. It makes the devil irrelevant, as it was God who decreed that he caused the fall. Our Lord Jesus Christ plainly identified those who continually reject and oppose His message as being among those He came to save (John 12:47-48), which violates any notion of limited atonement. Neither does the grafting or severing from the root of salvation that the Apostles Paul speaks of in Romans 11:16-25 make sense if unconditional election is true.
