Believers are SAVED people. Who believe the gospel of your salvation. That Christ died for our sins, was buried, and rose again the third day. Believers, those who are saved because they believed in the Gospel of Your Salvation, are sealed by the Holy Spirit unto the day of redemption. Not UNTIL, but UNTO. (Eph. 4:30).
Those who have been saved from death - for certain - are not living, you included.
Who believe the gospel of your salvation.
With double predestination or without?
Believers, those who are saved because they believed in the Gospel of Your Salvation
How long did they believe and how much did they believe? How long will you believe what you believe is necessary for salvation, and how much will you believe it? How much will your belief be tested? How do you know how much and what you what you will really believe then?
Who is the judge of your salvation?
