Ultimately, when you stand before the Lord face to face, He will not ask what someone else told you but will hold you accountable for what you yourself believe. Continue without striving or panic but with quiet trust to seek the Lord about matters that trouble you until you are deeply satisfied with His answer. He’s the One from whom perfect answers come.
"But why dost thou judge thy brother? or why dost thou set at nought thy brother? for we shall all stand before the judgment seat of Christ."
