Doubt is to call into question the truth of: to be uncertain.
Some storms are so overwhelming that they, threaten not only our peace of mind, shake our Faith in God, and wreck havoc on our belief system. As humans our faith is not always free from imperfection. Jesus knows all about our struggles as He had to, on several occasions, rebuke His disciples considering their level of faith, or lack thereof; unbelief. However, no matter what it seems like, to you, always remember Jesus is the One Who saves us, and stills the storm.
"And, behold, there arose a great tempest in the sea, insomuch that the ship was covered with the waves: but he was asleep. And his disciples came to him, and awoke him, saying, Lord, save us: we perish. And he saith unto them, Why are ye fearful, O ye of little faith? Then he arose, and rebuked the winds and the sea; and there was a great calm (Mathew 8:24-26).
Remember, We Are God's Witnesses
God said, “You are my witnesses,” declares the LORD, “and my servant whom I have chosen, so that you may know and believe me and understand that I am He. Before Me no god was formed, nor will there be one after Me (Isiah 43:10). "For I reckon that the sufferings of this present time are not worthy to be compared with the glory which shall be revealed in us (Romans 8:18)."Let us hold fast the profession of our faith without wavering; (for he is faithful that promised;) (Hebrews 10:23).
Believe, Hold Fast To The Faith!
