Rom.14[7] For none of us liveth to himself, and no man dieth to himself.
[8] For whether we live, we live unto the Lord; and whether we die, we die unto the Lord: whether we live therefore, or die, we are the Lord’s.
[9] For to this end Christ both died, and rose, and revived, that he might be Lord both of the dead and living.

We are not our own. We belong to the Lord and as belonging to Him we are to glorify the Lord in whatever we do. If it is good times or bad times we still are duty bound to give God glory. This surely is the better testimony to those around us is we still remain faithful and give God glory when we are in the midst of chaos.
Certainly we get tired of the stress of this world but we must remember we do not belong to this world and this is not our home. (1 Corinthians 6:20) Most assuredly when it is time for us to be at rest and go home to be with the Lord He will surely take us there. But until that moment we must strive to be what He wants us to be. Each day being more conformed to the image of Christ.

The fact we are still hear is evidence to us that God is not through we us. We still have a purpose in His plans. We might not see it or know to what extent He will use us but we know His timing is perfect.

Phil.1:[21] For to me to live is Christ, and to die is gain.
[22] But if I live in the flesh, this is the fruit of my labour: yet what I shall choose I wot not.
[23] For I am in a strait betwixt two, having a desire to depart, and to be with Christ; which is far better:
[24] Nevertheless to abide in the flesh is more needful for you.
[25] And having this confidence, I know that I shall abide and continue with you all for your furtherance and joy of faith;
[26] That your rejoicing may be more abundant in Jesus Christ for me by my coming to you again.

Our mission on this earth is not for the fleeting pleasures it has to offer but to show Christ to those around us. God deals in eternity and we as His children are not to be seeking the mammon of this life but laboring for those treasures in Heaven and in eternity. We must ever keep in the forefront of our mind that everything in this world is temporal and the things we do in the name of the Lord bears eternal rewards.
For a Christian to live is indeed CHRIST.

2Cor.3:[1] Do we begin again to commend ourselves? or need we, as some others, epistles of commendation to you, or letters of commendation from you?
[2] Ye are our epistle written in our hearts, known and read of all men:
[3] Forasmuch as ye are manifestly declared to be the epistle of Christ ministered by us, written not with ink, but with the Spirit of the living God; not in tables of stone, but in fleshy tables of the heart.
[4] And such trust have we through Christ to God-ward:
[5] Not that we are sufficient of ourselves to think any thing as of ourselves; but our sufficiency is of God;
[6] Who also hath made us able ministers of the new testament; not of the letter, but of the spirit: for the letter killeth, but the spirit giveth life.

We may not realize the influence our life has on those around us but God does. According to His word we are His word to those around us and based on His word we are aware that others watch us and see the proof of our testimony. This is the duty of everyone born of the Spirit.

Philippians 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.
[13] For it is God which worketh in you both to will and to do of his good pleasure.
[14] Do all things without murmurings and disputings:
[15] That ye may be blameless and harmless, the sons of God, without rebuke, in the midst of a crooked and perverse nation, among whom ye shine as lights in the world;
[16] Holding forth the word of life; that I may rejoice in the day of Christ, that I have not run in vain, neither laboured in vain.
[17] Yea, and if I be offered upon the sacrifice and service of your faith, I joy, and rejoice with you all.
[18] For the same cause also do ye joy, and rejoice with me.

We are the light in a dark and dying world. There are those that each of us as individuals have impact on which other Christians do not. This is why God has seen fit to leave us here. Not for our own pleasure but to be the influence on others. The world is without hope as we are admonished in the book of Ephesians.
