Test and prove yourselves

"Examine and test and evaluate your own selves to see whether you are holding to your faith and showing the proper fruits of it.  Test and prove yourselves [not Christ].  Do you not yourselves realize and know... that Jesus Christ is in you - unless you are [counterfeit] disapproved on trial and rejected?" II Corinthians 13:5 AMPC

There's not a better way to put it: Examine and test and evaluate yourselves daily to see if there is anything, (sin, wrong thinking, darkness, depression, etc.), in you that needs to be removed.  If there is, and as humans we usually have something dark within, then we need to repent, and ask the Lord to remove it from us; ask the Lord to change our thoughts and actions.  I believe that it is so important for us to stay on our toes when it comes to sin and darkness that we hold on to.  In my opinion, it is what we hold on to that leads us to, or away, from God, so consistent accountability to God of our thoughts and actions is a must.  

Remember, God lives within you!  You are so unique, and so special - you have so much to offer this world.  So, don't let the dark-side of life get the best of you - don't let go of God, not even for a second.  Soon, your inner Light and beauty will come out naturally, you will have more confidence because of the Spirit within you, and the devil will stay further and further behind you, knowing that you are getting too strong for him to even want to deal with.
