As imperfect beings, we have defects both inside and outside the body, there are people who detail a lot the outside of people and how is the appearance of others, so much that they forget theirs.
In both earthly and spiritual life, we have that great flaw: "judge others."
As human beings, we have so many defects that we must erase from our lives and change to look more like God, but this defect hurts us spiritually.
If we judge others, we do not expect to receive anything better from them, if we work so hard on the imperfections of others, we do not expect to receive anything better than what we deliver.
Matthew 7: 1 | NIV
Do not judge anyone, so that no one judges you.
As believers, we must see only our mistakes, because at the end of the day, to be a better believer, you have to change yourself. And yes, it is difficult for us to focus only on ourselves, not seeing the mistakes of others.
Romans 2: 1 | NIV
Therefore, you have no excuse, whoever you are, when you judge others, because in judging others you condemn yourself, since you practice the same things.
We have no excuses to judge others, when we make mistakes ourselves, we cannot help someone else, when we ourselves are damaged.
I think that, as people, it is better to see others make mistakes and think that I do not make the best decision, to see ourselves making mistakes and having no idea what to do.
Matthew 7: 3 | NIV
Why do you look at the splinter that your brother has in his eye and do not give importance to the ray that is in yours?
At the end of all, as believers we should know that salvation is individual, that we should only focus on ourselves to fulfill what God commands us, and thus be able to help those who need you, just "look in a mirror and you" will see what you need to change. "
