In my many years as a “born-again” believer in the Lord Jesus Christ, I am deeply concerned about believers who once “ran well” with a love, passion, joy, and enthusiasm for the Lord, but somehow strayed from the “Christian pathway.” Apparently, they must have taken their eyes off the Lord and instead focused on the things of this world and ceased to live a godly life.
Because of His foreknowledge, God knew that there would come the time when “some will depart from the faith,” hence in writing to Timothy, the Apostle Paul stated, “In latter times some will depart from the faith, giving heed to deceiving spirits and doctrines of demons” (1 Timothy 4:1,2).
The scripture exhorts Christians to “set your hearts on things above, where Christ is seated at the right hand of God. Set your minds on things above, not on earthly things” (Colossians 5:1-3). And, Paul continues his exhortation, “For you died, and your life is now hidden with Christ in God.” Being born again means exactly what God says, and that is, “If anyone is in Christ, he is a new creation; old things have passed away; behold, all things have become new” (2 Corinthians 5:17). "For you died" means you trust Jesus Christ as your Savior.
This present world is filled with enticements and attractions that some Christians who stand for nothing and fall for everything will “depart from the faith.” However, the good thing is that, contrary to the belief of some, these Christians “cannot lose their salvation.” The Bible is very clear: “nothing will be able to separate us from the love of God that is in Christ Jesus our Lord” (Romans 8:39). And there are other references in support of this truth. However, we can certainly lose the “joy of God's salvation” as King David did. He prayed, “Restore to me the joy of your salvation and uphold me with a willing spirit” (Psalm 51:12).
