Juan, you are not alone nor should be ashamed for feeling this way... even Peter sank...but, he had a testimony that no other could take away... he still walked on water, even though it was just for a moment!!!.and ya know what? ..even though he show'd a little lack of faith when he saw the winds and waves, the Lord didnt let him sink, He reach out his hand and saved him... that hand is there for you too!!! ...When the enemy comes in like a flood, The Spirit of the Lord will lift up a standard against him. (Isaiah 59:19)
