Dear Kaykel, even though when you see changes, and that's some evidence for own assurance... this is still to walk by sight, and a trap into which many of us fall. We're supposed to trust in God, that He's going to bring us where He wants us to be. When we exercise this confidence in God (as opposed to confidence in ourselves) is when the Spirit is flowing and progress happens. How many deeds or changes are "good enough"? The fact is that we are all a work in progress, and the fundamental problem with salvation insecurity is lacking faith. If one lacks faith, no assurances will be enough and doubts will remain - if you look at atheists this is very clear. You can reason with them all day long the reality of intelligent design, but they cannot believe. It's important to truly acquire assurance. But, I've come to believe that the way of acquiring it is not by constantly monitoring our works. At some point, we have to put trust in God's character and forfeit obsessing about ourselves all the time; imagine if a soldier in battle started overthinking at every turn what might happen to him and is he fit to be in the unit, as opposed to being present. This is an ineffective soldier and this is why it's a trap. This just spiritually paralyzes people, rendering them ineffective, and God doesn't want unfruitful things like this for us. We don't need to be running in circles and condemning ourselves any more. God's Spirit will search us as He sees fit, and remove what He sees fit.
