What have we become?

Although the question, "what have we become" isn't totally accurate, cause this is what we have always been. More and More i see Christians with the idea, that they can go through life, witnessing, and doing no study. Yeah they know the basics, they know what they learned in Sunday school, and go to church regularly, but they don't study, they are content with being at the point in the Christian walk they are...they are doing just that walking. The bible says it is a race, no not one to be competitive and beat other Christians to the goal, but to race towards the goal, as a unit, one body, one father, one Church, one bridegroom. In Philippians Paul says

13Brothers, I do not consider that I have made it my own. But one thing I do: forgetting what lies behind and straining forward to what lies ahead, 14I press on toward the goal for the prize of the upward call of God in Christ Jesus.

Paul, admits he "hasn't made it his own" or gotten there yet, but he is straining and pressing on, yet we as Christians don't do these things. I am not saying all Christians, i am saying many, including myself, i do not believe the argument of "you do the same thing so thus you cannot say it is wrong", nor do i believe the argument of "well, even Christians sin"
We as Christians do sin, but we shouldn't EVER use that as an excuse for incorrect behavior of oneself or someone else. In second Peter is says this

5For this very reason, make every effort to supplement your faith with virtue,^[e] and virtue with knowledge, 6and knowledge with self-control, and self-control with steadfastness, and steadfastness with godliness, 7and godliness with brotherly affection, and brotherly affection with love.

These are the things you should see in Christians, and they should be striving for them, but i also feel some people take one part of the list and "run with it" many men want to be "good" but they have no knowledge of God, or are controlled, but have no faith etc.

8For if these qualities^[f] are yours and are increasing, they keep you from being ineffective or unfruitful in the knowledge of our Lord Jesus Christ.

but notice it says these, meaning plural, not just one, if we don't have ALL of these we are unfruitful.

9For whoever lacks these qualities is so nearsighted that he is blind, having forgotten that he was cleansed from his former sins.

Yes, Christians become unfruitful, we become lazy, we forget what He has done for us, and live our lives "for God" but as long as we don't have to move any further in the relationship, but that isn't what we are called to, and peter says this is why he reminds us of this.

10Therefore, brothers,^[g] be all the more diligent to make your calling and election sure, for if you practice these qualities you will never fall. 11For in this way there will be richly provided for you an entrance into the eternal kingdom of our Lord and Savior Jesus Christ.

12Therefore I intend always to remind you of these qualities, though you know them and are established in the truth that you have. 13I think it right, as long as I am in this body,^[h] to stir you up by way of reminder, 14since I know that the putting off of my body will be soon, as our Lord Jesus Christ made clear to me. 15And I will make every effort so that after my departure you may be able at any time to recall these things.

"Peter says, if we practice these qualities we "will never fall" that got me thinking, "that isn't true, we are sinful, we will always fall" but that is a promise, if we TRULY do that we will NEVER fall. So why don't we do it?
