You need a special revelation from Satan to believe that Salvation is not eternal. Salvation is as simple as Joh.3:16. Eternal Insecurity is a ruse.

ETERNAL SECURITY is the good the shed blood of Jesus deliver for believer in Christ. Heb.10:10,14,Joh.3:18,5:24, Salvation is eternal.

When I was believing the error of eternal insecurity, my life was full of secret sin due internal fear, insecurity, low self esteem, self righteousness, weak confidence etc.
When I embraced the truth of the gospel, I was freed from all my secret sins by the power of the Holy Spirit.
Baba Adeboye. Your theory that those who believe eternal security are battling secret sins is untru. The opposite is actually the truth.

If the man than that died for me said I am ETERNALLY SECURED and the man that needs my offering says I am not, I know who to believe.
