Who has room to judge and criticize you?!?!

Do not judge and criticize or condemn others, so that you may not be judged, criticized and condemned yourselves.   For just as you judge, criticize and condemn others, you will be judged, criticize and condemned in accordance with the measure you deal out to others, it will be dealt out again to you.        Matthew 7:1-Two 

We judge and criticize in others what we do not like about ourselves. The devil likes to keep us busy by  identifying and judging the faults of others. In hopes that we never see or deal with our own personal issues.   When we focus our thoughts or talk about the flaws and faults of others, we deceive ourselves about our own conduct. This is why Jesus commands that we not concern ourselves with the wrongs of others when we are flawed and faulty ourselves. 

It's true that you do not have the power to change others or yourself, only God can.

If you truly want to help someone change, then don't be judgmental about it.  Be an example of that change. Allowing God to deal with you first, then be a humble and loving example of that change.  When sharing your process with others  try to be open and honest  about how you were able to accept your own personal challenges and flaws. That way someone may identify and relate to your personal struggles, seeking God for change. If you're choosing to seek change, it should always be a personal choice. Something that should be done not out of  obligation but because of love. Someone who feels obligated to change may seek it temporally only to return back to their old habits and behaviors. But choosing to changing because of love is felt in the heart. This is the place where God wants us to  change first. He wants you to change on the heart level  because this is a lasting change.  You learn to not judge or criticize others base off of your own flawed thinking, but seek to understand them better.

We may not like everyone we come in contact with but that does not give us the right to judge them.

Instead of focusing on what you dislike about a person. Find something that you like and focus on that.

We should not use our judgment as a way to  criticize and attack someone personally. True judgment only comes from God. This is when the Holy Spirit convicts us about something we have done in hopes for us to notice our behavior and change it.
