He has taken care of everything, and the proof is in the Cross:
"1Now I Paul myself beseech you by the meekness and gentleness of Christ, who in presence am base among you, but being absent am bold toward you: 2But I beseech you, that I may not be bold when I am present with that confidence, wherewith I think to be bold against some, which think of us as if we walked according to the flesh. 3For though we walk in the flesh, we do not war after the flesh: 4(For the weapons of our warfare are not carnal, but mighty through God to the pulling down of strong holds;) 5Casting down imaginations, and every high thing that exalteth itself against the knowledge of God, and bringing into captivity every thought to the obedience of Christ; 6And having in a readiness to revenge all disobedience, when your obedience is fulfilled." (2 Corinthians 10: 1-5)
We have to revisit the truth that the weapons are not carnal, they are not our flesh.
They have nothing to do with our physical efforts or our feelings.
They are all based on His Spirit:
"Then he answered and spake unto me, saying, This is the word of the LORD unto Zerubbabel, saying, Not by might, nor by power, but by my spirit, saith the LORD of hosts." (Zechariah 4: 6)
"It is the spirit that quickeneth; the flesh profiteth nothing: the words that I speak unto you, they are spirit, and they are life." (John 6: 63)s
"But we all, with open face beholding as in a glass the glory of the Lord, are changed into the same image from glory to glory, even as by the Spirit of the Lord." (2 Corinthians 3: 18)
We do not fight with the ideas of men, but the Wisdom of God:
"And take the helmet of salvation, and the sword of the Spirit, which is the word of God:" (Ephesians 6: 17)
We are called to allow the weapons of God to bring the thoughts into captivity to the obedience of Christ. Not some idea or imagination, but the true and verified account and reality.
Notice that it is not "Obedience to Christ". It's all about what Jesus has done for us:
"5Let this mind be in you, which was also in Christ Jesus: 6Who, being in the form of God, thought it not robbery to be equal with God: 7But made himself of no reputation, and took upon him the form of a servant, and was made in the likeness of men: 8And being found in fashion as a man, he humbled himself, and became obedient unto death, even the death of the cross. 9Wherefore God also hath highly exalted him, and given him a name which is above every name: 10That at the name of Jesus every knee should bow, of things in heaven, and things in earth, and things under the earth; 11And that every tongue should confess that Jesus Christ is Lord, to the glory of God the Father." (Philippians 2: 5-11)
He died on the Cross for our sins, and was raised for our justification.
Today, He is seated at the right hand of God our Father, and sits are our perfect man, our perfect representative, a High Priest Forever, forever justifying us from all our sins:
"23Now it was not written for his sake alone, that it was imputed to him; 24But for us also, to whom it shall be imputed, if we believe on him that raised up Jesus our Lord from the dead; 25Who was delivered for our offences, and was raised again for our justification."
Indeed, Jesus was raised for our justification, and today He sits at the right hand of God our Father:
"19And what is the exceeding greatness of his power to us-ward who believe, according to the working of his mighty power, 20Which he wrought in Christ, when he raised him from the dead, and set him at his own right hand in the heavenly places, 21Far above all principality, and power, and might, and dominion, and every name that is named, not only in this world, but also in that which is to come: 22And hath put all things under his feet, and gave him to be the head over all things to the church, 23Which is his body, the fulness of him that filleth all in all." (Ephesians 1: 19-23)
We bring out thoughts into Captivity to the Obedience of Christ: His death, His resurrection, and His ministry today and forever.
