“Whoever believes in the Son has eternal life; whoever does not obey the Son shall not see life, but the wrath of God remains on him.” (John 3:36, ESV)
Yesterday we learned from this verse that whosoever believes in the Son “has eternal life” precisely because one obeys the Son. One who “does not obey the Son” is under God’s wrath instead of life. There is one more thing worth our consideration here. Many who believe one is saved “by faith alone” also believe in the impossibility of apostasy (“once saved, always saved”). However, if it is true that once the believer has eternal life he will always have life and never lose it – even if he becomes disobedient – then it necessarily follows the disobedient unbeliever can never escape the wrath of God that “remains on him.” To believe “once saved, always saved,” one must (according to this view of John 3:36) also believe “once lost, always lost.” (We are aware Calvinistic theology accepts these conclusions.) However, the gospel does not. It is for all (Mk. 16:15). God desires the salvation of every sinner (1 Tim. 2:3-4). Freewill enables us to choose to hear, believe, and obey the gospel to be saved (Acts 2:21-22, 37-41; 17:30). It also allows us to choose to sin and fall from grace (Gal. 5:4; 2 Pet. 2:20-22). Security in Christ is sure when we obey in faith: “Therefore, brethren, be even more diligent to make your call and election sure, for if you do these things you will never stumble; for so an entrance will be supplied to you abundantly into the everlasting kingdom of our Lord and Savior Jesus Christ” (2 Pet. 1:10-11).
