"For in Him [Christ] all the fullness of Diety dwells in bodily form, and in Him you have been made complete, and He is the head over all rule and authority;" -Colossians 2:9-10
Every true Christian is complete in Christ, which means that they lack nothing and nothing can shake their identity in Christ. And since Christ is above all other authority, no authority can take away from that completeness. Neglect, misunderstanding, slander, mistreatment, or worse by anyone else cannot shake that completeness. True? Why then is it so common for us Christians to get impatient, offended, proud, angry, and worse with each other? Why this touchiness and defensiveness if my completeness has nothing to do with me or my critics? The whole issue is about setting your mind on Christ as your completeness. Every bad reaction you have is rooted in distraction, ignorance, or forgetfulness of your identity in Christ.
Are you persuaded that this is true? God loves you and delights to help you learn this lesson of love. All your critics and all your troubles are HIS messengers to help you notice and keep focused on your identity in Christ. The last time you were disagreed with, criticized, mocked, or neglected by a fellow Christian, did you embrace such as grace from God, giving Him thanks for your and your critic's completeness in Christ? Did your critic receive a warm saintly welcome from you and maybe even an invitation to expand on the criticism? Did you embrace such as a good opportunity for YOU to learn more about YOUR own weaknesses? Did you see God's smile of delight on that dear saint WHILE you were being mistreated? Or, did you think in terms of your own rights, and respond defensively? The truth about your completeness in Christ while you are being a jerk to others, is also true of others WHILE they are being jerks to you. True? If you thank God often that this is always true for all Christians, it will be more natural for you to remember it in the heat of the moment.
Practice remembering your security in Christ and watch your reactions change.
