"Do not judge, or you too will be judged. For in the same way you judge others, you will be judged, and with the measure you use, it will be measured to you. Why do you look at the speck of sawdust in your brother's eye and pay no attention to the plank in your own eye? How can you say to your brother, 'Let me take the speck out of your eye,' when all the time there is a plank in your own eye? You hypocrite, first take the plank out of your own eye, and then you will see clearly to remove the speck from your brother's eye." Matthew 7:1-5
This passage doesn't mean that all types of judgment are wrong. In fact, elsewhere Jesus tells us to make right judgments, and Jesus Himself judges (albeit, He is perfect and therefore is the only one with the authority to judge all others) others. Jesus is here telling His disciples not to be be judgmental, which is a lot different than making judgments.
As far as the plank in your eye, well, just remember that you can only lead others as far as you're willing to go yourself. If you're not seeking Christ, then don't try to help a brother or sister try. First, focus your heart, mind, and strength on Him, and then you'll be fit to assist others on their journey.
May you, today, make right judgments, focus your entire being on Christ, and lead others to do the same.
