Jesus said, "Judge not, that you be not judged. For with what judgement you judge, you will be judged; and with the measure you use, it will be measured back to you."-- Matthew 6:23
I did not invent this, but Jesus said this Himself in the New Testament of the Holy Bible. This is just one of the many Bible texts that many of us can apply in our daily lives. There's a lot more from the Bible.
Read the Holy Bible yourself if what I just quoted is true. If you wish to have a Holy Bible for yourself, you can buy online at The Bible Source.
