And he that doubteth is damned if he eat, because he eateth not of faith: for whatsoever is not of faith is sin. Romans 14:23 KJV
I’m a believer, not a doubter. I hope that you are too, because it is impossible to please God without faith.
But without faith it is impossible to please him: for he that cometh to God must believe that he is, and that he is a rewarder of them that diligently seek him. Hebrews 11:6 KJV
However, with faith in God, there is nothing impossible for you.
And Jesus answering saith unto them, Have faith in God. For verily I say unto you, That whosoever shall say unto this mountain, Be thou removed, and be thou cast into the sea; and shall not doubt in his heart, but shall believe that those things which he saith shall come to pass; he shall have whatsoever he saith. Therefore I say unto you, What things soever ye desire, when ye pray, believe that ye receive them, and ye shall have them.
Mark 11:22-24 KJV
