Full assurance is not essential to salvation, but it is essential to satisfaction. May you get it-may you get it at once. May you never be satisfied to live without it. –Spurgeon
And these things write we unto you, that your joy may be full. 1 John 1:4
A full assurance of your salvation brings about a full life of joy! That’s the problem with some Christians though, they don’t spend time in the Word getting the assurance they need to have joy in their soul! I’ve got joy like a river flowing in my soul—How about you?
