All Christians should be confident of their security in Jesus Christ. The following passage explains in detail just how secure we are in Him.
“What shall we then say to these things? If God be for us, who can be against us? He that spared not his own Son, but delivered him up for us all, how shall he not with him also freely give us all things? Who shall lay any thing to the charge of God's elect? It is God that justifieth. Who is he that condemneth? It is Christ that died, yea rather, that is risen again, who is even at the right hand of God, who also maketh intercession for us. Who shall separate us from the love of Christ? shall tribulation, or distress, or persecution, or famine, or nakedness, or peril, or sword? As it is written, For thy sake we are killed all the day long; we are accounted as sheep for the slaughter. Nay, in all these things we are more than conquerors through him that loved us. For I am persuaded, that neither death, nor life, nor angels, nor principalities, nor powers, nor things present, nor things to come, Nor height, nor depth, nor any other creature, shall be able to separate us from the love of God, which is in Christ Jesus our Lord.” (Romans 8:31-39 KJV)
There is a lot covered in those few verses. Often we become concerned about the condition of our world, or anything about us. Things of this life are unworthy of our deep concern and worry. Notice this sentence by Paul in the above quote: "shall tribulation, or distress, or persecution, or famine, or nakedness, or peril, or sword?" These are things he is asking us if they will separate us from the love of Christ.
But when you stop and consider that none of these things are of the utmost importance when compared to our promise of life eternal in the presence of God and His Son. If we compare our life with that of Paul, the chances are that his personal problems were much more serious than ours. Certain ones had apparently ridiculed Paul to the Christians at Corinth, but in chapters 11 and 12, of his 2nd epistle, he spells out to them the difficulties he has faced and the great lengths he had gone in order to be certain that he did not burden them with his upkeep. The reader is encouraged to read those two chapters in order to help them understand the confidence he had in Jesus. Read chapter 11. And chapter 12.
When we grow in Christ to the degree that living for Him is the most important thing in our lives, we can be as Paul when he again implores us to:
“Be careful for nothing; but in every thing by prayer and supplication with thanksgiving let your requests be made known unto God. And the peace of God, which passeth all understanding, shall keep your hearts and minds through Christ Jesus. Finally, brethren, whatsoever things are true, whatsoever things are honest, whatsoever things are just, whatsoever things are pure, whatsoever things are lovely, whatsoever things are of good report; if there be any virtue, and if there be any praise, think on these things.” (Philippians 4:6-8 KJV)
Notice especially the first phrase in that passage. "Be careful for nothing," simply means do not worry about anything just as long as you are living for Jesus Christ. Even though life may seem long and many trials come our way, remember scriptures such as Job's remarks:
"Man that is born of a woman is of few days, and full of trouble. He cometh forth like a flower, and is cut down: he fleeth also as a shadow, and continueth not." (Job 14:1-2 KJV)
Perhaps no one has ever had everything of value taken away from them as did Job, his wealth and holdings, his children and his health, yet he did not sin against God and perhaps he made one of the most meaningful and humble remarks that anyone ever made under such dire circumstances. After he had been informed of his terrible losses he had this to say...read it carefully:
"Then Job arose, and rent his mantle, and shaved his head, and fell down upon the ground, and worshipped, and said, Naked came I out of my mother's womb, and naked shall I return thither: the LORD gave, and the LORD hath taken away; blessed be the name of the LORD. In all this Job sinned not, nor charged God foolishly." (Job 1:20-22 KJV)
