Yes, these "emotions" are "huge problems," IF one is not in Christ! However, "IF Christ dwells within you" - No Problem! The problem is, MOST don't "BELIEVE" all of His Word rather take it upon themselves to "fix the problem" without the "Help" of the Holy Spirit!
Let's see what the "Creator" (GOD) of the universe has to say about these "emotions" vs what "man" says:
I. "Fear:" Fear and anxiety are two "emotional" tools used by Satan! If one "BELIEVES" in His Word, we MUST "stand" on what HE has said! Isaiah 41:10 tells us "Fear thou not; for I am with thee: be not dismayed; for I am thy God: I will strengthen thee: yea, I will help thee with the right hand of my righteousness." "Yea, though I walk through the valley of the shadow of death, I will fear no evil: for thou art with me..."(Psalm 23:4)! WOW! If we would "stand" on His Word, "Believing" in what HE has said, we would KNOW "No weapon (Satan) formed against me will prosper" (Isaiah 54:17)!
II. "Insecurity:" When we feel "insecure" it only displays our lack of confidence and trust in what GOD has said (unbelief). Obviously, another "emotional" tool used by Satan! "In him and through faith in him we may approach God with freedom and confidence" (Ephesians 3:12). "But blessed is the one who trusts the LORD, whose confidence is in him" (Jeremiah 17:7)! We can then "...come "Boldly" unto the throne of grace, that we may obtain mercy, and find grace to help in time of need" (Hebrews 4:16).
III. "Intolerance:" GOD is an "Intolerant" GOD so why aren't we? "Thou shalt have NO OTHER gods before me" (Exodus 20:3). This is what the "Creator" of the universe said! The GOD of Abraham, Issac and Jacob! So why do we "worship" other gods?
His saying was also "carried over" into the NEW COVENANT in which He said (speaking through Paul as HE spoke through The Prophets) "But though we, or an angel from heaven, preach any other gospel unto you than that which we have preached unto you, let him be "ACCURSED." As we said before, so say I now again, If any man preach any other gospel unto you than that you have received, let him be "ACCURSED" (Galatians 1:8-9)!
This is what GOD (The Creator of the universe, the GOD of Abraham, Issac and Jacob) has said!
IT IS WRITTEN!
