I let that stand a few minutes to follow up with this. I don't know where folks here are in knowledge of scriptures, so I can only type what I feel is a good direction for most folks. Romans 14 might seem advanced because it is near the end of a magnificent book, but that chapter is one good for Christians at all "ages" of understanding, and helps us each deal with people of diverse denominations to be civil with each other, not doing what so many did before us, disputing to the point of creating yet another denomination.
The setting is the issue of whether to go ahead and eat, or drink, or observe holy days and the like when witnesses are around who are strong in the faith as well as those weak in the faith or have no like beliefs at all, each mutually capable of being offended by the other. At the close of it is a startling verse which I will post here hoping upon hope you will read the whole chapter 14. Without the whole of it you will not get this verse rightly understood or applied in life, but you will be presented it often out of context.
Romans 14:23 (KJV) [SUP]23 [/SUP] And he that doubteth is damned if he eat, because he eateth not of faith: for whatsoever is not of faith is sin.
It makes being afraid of God after knowing Him, who commands believers to not be afraid, to be sin. No Christian should be terrified over this, but take action to stop doing it, then fully enjoy the Kingdom privileges. We can base that on this from the continued sermon in chapter 15 with Romans 15:4 (KJV) [SUP]4 [/SUP] For whatsoever things were written aforetime were written for our learning, that we through patience and comfort of the scriptures might have hope.
It is Satan and or demons taking advantage of bad teaching that causes us to doubt and hide from God because we messed up. Adam and Eve did that, but God called them out of hiding and loved them more than they could possibly understand. Submit to God, resist the devil, and he will flee from you has conditions (in context), but applies here. Chapter 15 encourages you to be strong in the faith so you can encourage others who are weaker. You should not be strong in the faith just to be strong, but to help others enjoy the Kingdom of our Lord and God. When we focus on such things, thoughts of fear melt away. Just mentally dealing with that won't do much good for you or others. Face to face interact with someone needing your encouragement. That will empower you to replace fears with ministry, doing the good works that prove the reality of faith in you.
