Progressive Sanctification and God's Patience

My wife and I had a great conversation recently on struggling with sin. The question came up as to why God would save His people from their sin and yet somehow allow us to still sin. If I am really a redeemed creature, why wouldn't God make me perfect on Day 1? Why still allow me to sin against him and struggle daily? In my uber-finite human wisdom, it doesn't seem to make much sense as to why our Heavenly Father would allow his children to remain in the self-inflicted muck...

Now, certainly, God's will for me is perfection. Paul said as much: "By no means! How can we who died to sin still live in it? ... So you also must consider yourselves dead to sin and alive to God in Christ Jesus" (Romans 6:2, 12). But why in his great plan does he not immediately remove me not only from sin's punishment, but also from it's practice?

My answer to this question is from some bible inferences & my own experience. (If anyone has biblical support for this specific idea, please pass it along.) We know that all God does is to show his glory and thus receive the praise he is due. This can range from the creation of man (Is. 43:7), the creation of the heavens and earth (Ps. 19:1), to the salvation of mankind (Eph 1:3-14). So we know that God chose to not make us perfect right away and that this glorifies him somehow.

My estimate is this. God certainly had the power to make us perfectly holy right away. But it would not allow him to show the fullness of his discipline and patience that he, as Father, has on us, His children. If I never messed up in my family as a child, I would never have experienced the mercy & patience that sometimes my dad gave me by not dealing out a hefty swat. 

It is likewise with our Heavenly Father. Every time we stumble, "he is faithful and just to forgive us our sins and cleanse us from all unrighteousness" (1 Jn. 1:9). We see firsthand the patience of God as he leads us on to holiness, one step at a time. It is a patience that we would not experience in the same way if we were immediately made perfect upon our conversion. No, his patience does not excuse our all-too-frequent-sin- "What shall we say then? Are we to continue in sin that grace may abound?" (Rom. 6:1). But our status as an "already, but not yet, resurrected, fallen man" enables us to experience God in a deeper way, and praise him with a deeper passion, and shine for him with a brighter testimony.

Therefore, we claim with Paul, "But I received mercy for this reason, that in me, as the foremost, Jesus Christ might display his perfect patience as an example to those who were to believe in him for eternal life" (1 Tim. 1:16).
