Simple Question...

What have you done to progress or expand or enable the Kingdom of God here on Earth today?
Have you talked to someone about Him?
Have you passed out even one tract?
Have you read His word?
Have you worked to memorize a verse?
OR
Have you even represented Him in a Christ like manner? If people looked at you today, would it be obvious that you are set apart for Him and His glory? Or would the world simply say there goes one of us? Should we not feel ashamed if this is true of us?

We should question our salvation if we are not consistently conforming to His image.

Php 2:12 Wherefore, my beloved, as ye have always obeyed, not as in my presence only, but now much more in my absence, work out your own salvation with fear and trembling.

One thing we tend to forget, we are never truly not in His presence. We are called to workout our own salvation. What have you done to do so?

With fear and trembling... we are right to fear the wrath of God and should tremble. Also, we should tremble with excitement. Why? Because, one day we will be in His presence, with His people, in His kingdom... What a glorious day.

If we are saved... Why do we fear losing this earthly existence? This earthly, sinful shell of a body?

Eph 4:27 Neither give place to the devil. (KJV)
Ephesians 4:27 and do not give the devil an opportunity. (NAS)

If you are not making room for God, you are allowing the devil his opportunity!
