Mercy will always triumph over judgment. The Lord has shown you mercy, so you are to go and show mercy to others. If you judge others, the Lord will judge you in the same way you judged. This principle is the same as reaping and sowing. Mercy has been sown to you and you go and do the same, but if you judge, this will come back to you. Jesus explained in in the parable of the unforgiving servant.
Matthew 6:14 For if you forgive men their trespasses, your heavenly Father will also forgive you. 15 But if you do not forgive men their trespasses, neither will your Father forgive your trespasses.
