Accountability and Correction

Galatians 6:1-5
Brothers, if someone is caught in a sin, you who are spiritual should restore him gently. But watch yourself, or you also may be tempted. Carry each other's burdens, and in this way you will fulfill the law of Christ. If anyone thinks he is something when he is nothing, he deceives himself. Each one should test his own actions. Then he can take pride in himself, without comparing himself to somebody else, for each one should carry his own load.

Here's what I've been pondering...
[note- I'm not perfect. I'm not claiming to have it all together; if anything, this thought and pondering has sent me into even deeper evaluation of myself- asking God to search me, try me, and make me more like Him.]
The responsibility of the church is greater than just teaching. I've known this, but I'm REALLY getting to know this as people continue to live for this world and slip into thoughts of self-sufficiency.
There are two kinds of responses to 'correction' and I've experienced both in recent month/years when dealing with close friends. First response I've gotten when I've honestly talked to someone about their sin has to do with acceptance of the correction. This is the most 'healing' response. It's an awareness and brokenness of the spirit and heart and allows each party in the situation to become closer to each other and to the Lord. As the scripture above states, 'restoring some gently' is the key. When each party is acting out of love, great lessons are learned and the Lord is glorified. The Second response is much harder and causes much more hurt. When one party is defiant and submerged into selfishness, harm is caused in an emotional and spiritual state. How can you 'carry someone's burden and fulfill God's law' when someone's heart isn't open to hearing Truth? The one in sin must be broken and repentant (not necessarily toward the one who is speaking correction but to the Lord). Healing will never happen if a hardened heart grows, if time passes and no resolution or clarity of perspective is made, and the Lord is not glorified in ignorance and foolish continuance in sin. And this 'sin' may not even be obvious to others, it may be a self-absorbed, a slipping of focus on reality... that only those close to the person will see.
Either way... my conclusion is THIS CHRISTIAN LIFE IS HARD. We each have a great responsibility to hold each other accountable. My question is... how far do you keep pressing when someone is definant to this help, when someone won't let you in their life anymore, when someone won't let you carry that burden because they don't want you to know their next step into this pit of sin...
Do you give up?
If only we could all keep a God-sized-perspective, an open heart to correction, and desire for others to carry our ugly burdens. This correction can end in healing and a greater love for friends and the Lord, or it could end in hard feelings, an incorrect perspective of self and pushing people away unnecessarily.
I'm still understanding this process, but take comfort in God's correction in my own life and will continue to take notes of His will and His ways!
