And he shall go before him in the spirit and power of Elias, to turn the hearts of the fathers to the children, and the disobedient to the wisdom of the just; to make ready a people prepared for the Lord. And Zacharias said unto the angel, Whereby shall I know this? for I am an old man, and my wife well stricken in years. And the angel answering said unto him, I am Gabriel, that stand in the presence of God; and am sent to speak unto thee, and to shew thee these glad tidings. And, behold, thou shalt be dumb, and not able to speak, until the day that these things shall be performed, because thou believest not my words, which shall be fulfilled in their season. (Luke 1:17-20 KJV)
Have you deny the truth from words of your friend? Even though deny the truth is not a sinful thing, it sometimes hard to accept the truth of your spouse, your friend, or family member. As long as we’d waver the truth, it is hard to accept the truth.
Look at Zacharias. Even though he was a high priest of Israel, he had a hard time to accept the truth from Gabriel. Why? He either hard to believe that Gabriel was the angel of the Lord or that he hadn’t seen the angel physically in his lifetime until eight decades later. Whatever his reason was, he waved the words of Gabriel, which they came from God.
We need not to play believing or not with God’s words. Otherwise, there would be consequences to accountable our actions.
