When God allows us to see something contrary to His Word
Many times In our normal everyday lives God allows us to see with our natural eyes the sinful nature of others. He does this to see if we will judge and condemn or offer it back to Him as Prayer with a heart filled with faith and compassion.
Convicting others of sin is not our responsibility, it is the responsibility of Holy Spirit. If you will just stop for one moment, lay your personal soulish opinion aside. Then allow Father God through His Holy Spirit lead you and guide you into all truth Jesus (The Way, Truth and Life). He will breathe life into the situation as we speak life (Jesus) into the situation.
We are all sometimes bystanders who observe harsh things. Our course of judgment determines our innocence or guilt before God in the situation. Bearing good fruit to your account or rotten fruit.
Ask The Lord how to pray for the situation or person. He may give you a Scripture. He may lead you to pray for a day or longer. Do as He leads and watch how He changes life’s situations through His Love, Mercy and Grace.
Just make absolutely sure that you don’t call someone out and offend them by judging them.
