Paul asked Jesus himself this very question: He refered to it as a thorn in his side, that is, to be perfect in every area of life yet there is still faults...
Continuing, we see that just as Paul the apostle asked God three times to remove the thorn from his side, so Jesus asked His Father to remove the cup from Him if it be Godís will.
This was what Jesus said:
Matt 26:38-39 Then saith he unto them, My soul is exceeding sorrowful, even unto death: tarry ye here, and watch with me. And he went a little further, and fell on his face, and prayed, saying, O my Father, if it be possible, let this cup pass from me: nevertheless not as I will, but as thou wilt.
Matt 26:42 He went away again the second time, and prayed, saying, O my Father, if this cup may not pass away from me, except I drink it, thy will be done.
Matt 26:44 And he left them, and went away again, and prayed the third time, saying the same words.
Just as Paul the apostle asked God three times to remove the thorn from his side, so Jesus asked His Father to remove the cup from Him if it be Godís will.
2 Cor 12:7-8 And lest I should be exalted above measure through the abundance of the revelations, there was given to me a thorn in the flesh, the messenger of Satan to buffet me, lest I should be exalted above measure. For this thing I besought the Lord thrice, that it might depart from me.
I believe God answered His Son as He answered Paul. He said, My grace is sufficient for thee. (2 Cor 12:9)
Matt 26:41 Watch and pray, that ye enter not into temptation: the spirit indeed is willing, but the flesh is weak.
You see-Jesus Christ was one of us. He was IN THE FLESH.
Jesus Christ needed help from God the Father, just as we do.
Luke 22:42-43 Saying, Father, if thou be willing, remove this cup from me: nevertheless not my will, but thine, be done. And there appeared an angel unto him from heaven, strengthening him.
So as you can see, God uses these imperfections for good, just as he uses Satan to test and often times his negativity actually worked out for the good, all because of God.
If you are not sure about God, I encourage you to find a closed quiet space. Sincerely in your mind and heart and Soul, you CRY OUT out to God.
Say this: "God if you are there, hear me. I am lost and don't know what to do. I want to strive to be perfect but I know we all have a thorn in our side. Father God please give me Discernment, and allow for my eyes to see and for my ears to hear. So that I can do what I am supposed to do. In Jesus name, Amen."
Remember, God said "look under the rock, i am there" etc.. you see God is 'never far' and is 'always in the midsts' that is, just like a best friend who goes everywhere with you. Once you have the Discernment, you will be able to separate whats real and whats not.
God will come to you and send the Holy Spirit to help you.
In the past I have prayed like this for God to come into my heart, and let me tell you, the moment the words left my mouth my body was shook, as I became scare that God actually had heard my prayer.
Thank God that He did. Now I am able to tell you it is real and it is the truth.
