Two can play at this game:
"…we have confidence before God; and whatever we ask we receive from him, because we keep his commandments and do what pleases him. And this is his commandment, that we believe in the name of his Son Jesus Christ and love one another, just as he has commanded us." (1 John 3:21-23)
Scripture interprets Scripture, and 1 John 5:14 does not imply that assurance is wavering, soluble, or uncertain for as we pray to God for salvation and true faith, He will give it to us.
>For if we were, Paul would no call us to "work out salvation with fear and trembling"
But it is not us alone who works or us who starts working, but "God who works in you, both to will and to work for his good pleasure. "(Phil. 2:13)
>we would not be "saved by hope" for hope is "of things uncertian"
An unfortunate translation of Romans 8:24. We are saved in "this" hope which is written to be "not seen" not "not certain". Not seen because, while it is certain, more certain the sun rising again tomorrow, it has not yet been revealed fully to all. But what is "this hope"? "And not only the creation, but we ourselves, who have the firstfruits of the Spirit, groan inwardly as we wait eagerly for adoption as sons, the redemption of our bodies," the resurrection or the consummation of the promises of God. And faith in the the God of those promises, or "in this hope," is the thing 'by which we are saved. That same God is God who gives full, blessed assurance as He gives eternal life to those He has chosen to save. (John 10:28, Hebrews 10:19-25)
So no, 1 John 5:14 does not come close to proving against full, blessed, certain assurance.
