I am working on a theory. My heart has learned this lesson, the LONG HARD WAY but I am trying to develop it into something more solid.
Here is a trustworthy saying: If we died with him, we will also live with him; if we endure, we will also reign with him. If we disown him, he will also disown us; if we are faithless, he will remain faithful, for he cannot disown himself. Keep reminding them of these things. Warn them before God against quarreling about words; it is of no value, and only ruins those who listen. ~2Tim 2:11-14
Side track: Quarreling about words? What does that mean? Stirring words around and never getting to the real issue? Hmm, have to think about that.
OK, back to my theory. I spent decades of my life believing I was a failure. First, just as a human being and then after I became a Christian, I believed I was failing God.
Then God taught me, I am His work and He will not fail. I don't have to be afraid. Am I weak? Yes. Am I immature? Yes. Is my heart pure? No. Do I know how to love? No. Does He love me anyway? Yes. Will He finish the work He began in me? Yes.
I do not trust in my strength or my goodness or my maturity or my wisdom. Only He can save me. I do not rely on myself to figure anything out. Only He can guide me.
My theory: If we believe Jesus is the Son of God and that He came to save us and we are willing to do anything He asks of us (willing, not able...He will make us able in His time, Phil 2:13) we are not, and are incapable of being, failures. We can fail but we are not living, breathing, failures. Even in humongous struggles of sin and doubt. We are His masterpieces and we can trust in Him.
For we are God's masterpiece. He has created us anew in Christ Jesus, so that we can do the good things he planned for us long ago. ~Eph 2:10
O Lord, you are my God; I will exalt you and praise your name, for in perfect faithfulness you have done marvelous things, things planned long ago.
