Once you are saved are you always saved? If you are struggling with the idea that you can lose your salvation, consider Christ’s own words on the matter in John 6:37-40.
John 6:37-40 NASB “All that the Father gives Me will come to Me, and the one who comes to Me I will certainly not cast out.  “For I have come down from heaven, not to do My own will, but the will of Him who sent Me.  “This is the will of Him who sent Me, that of all that He has given Me I lose nothing, but raise it up on the last day.  “For this is the will of My Father, that everyone who beholds the Son and believes in Him will have eternal life, and I Myself will raise him up on the last day.”
One cannot make this clearer than Christ has, but there are some interesting things to note. Verse 37 is the “topic sentence” if you will. It is a stand-alone verse concerning the issue of eternal security in Christ. Christ says ALL that the Father gives to Him will come to Him and ALL that come to Him will not be cast out… certainly! Not only does He say He will not cast anyone out, in verse 39 He says He will not lose anyone either.
Christ will not cast anyone out.
No one who has come to Christ will be cast out by Christ’s actions nor will they be cast out because of their own actions or the actions of another.
Christ will not lose anyone.
No one who has come to Christ will be lost by Christ’s actions or because of their own actions or the actions of another [John 10:28-29, Romans 8:38-39].
- All the Father gives to Christ will come to Christ 
- Those who come will not be cast out 
- Those who come will not be lost 
- All of those who come will have eternal life 
So what does this mean for you as a believer in Christ?
Christ will not cast anyone out nor will He lose anyone who comes to Him. Christ will not cast you away by His action, nor will He lose you because of your own actions or the actions of another. You, Christian, are secure in Christ. He promises.
