Why do Christians often judge one another? Christians are at different levels of spiritual maturity.
Leave the judgment up to God. Why do you judge and criticize your brother?
Why do you despise and look down upon your brother? So many believers stand guilty before God.
The person being criticized and judged is created by God. Why do we set ourselves up as God and criticize and judge others? We will all stand before the judgment seat of Christ.
Every knee shall bow to Christ. Every tongue shall confess to God. None of us are God and we have no right to judge and criticize another person.
"For it is written, As I live, saith the Lord, every knee shall bow to me, and every tongue shall confess to God" (Romans 14:11).
"Wherefore God also hath highly exalted him, and given him a name which is above every name: that at the name of Jesus every knee should bow, of things in heaven, and things in earth, and things under the earth; and that every tongue should confess that Jesus Christ is Lord, to the glory of God the Father" (Phil. 2:9-11).
We are not going to be called to give an account of another person before God. We must give an account of ourselves.
"For the Father judgeth no man, but hath committed all judgment unto the Son" (John 5:22).
"Because he hath appointed a day, in the which he will judge the world in righteousness by that man whom he hath ordained; whereof he hath given assurance unto all men, in that he hath raised him from the dead" (Acts 17:31).
Every single believer is to be constantly looking at his own life making sure that he is not putting a stumbling block in his brother's path to God, not even a single obstacle or hindrance of any kind.
We do not have time to judge and talk about our brother. We must walk in love toward our brother. Our circumstances do not define us and we must not try to define others by their circumstances.
"Let no man seek his own, but every man another's wealth [welfare]" (1 Cor. 10:24).
"If ye fulfil the royal law according to the scripture, Thou shalt love thy neighbour as thyself, ye do well" (James 2:8).
Christ died for all. If Christ loved all enough to die for all, then we must love each other enough to esteem each other before ourselves.
"And you, that were sometime alienated and enemies in your mind by wicked works, yet now hath he reconciled in the body of his flesh through death, to present you holy and unblameable and unreproveable in his sight" (Col. 1:21-22).
Ultimately our belief system informs and directs our behavior.
