A Christian is a stranger/a pilgrim in this world. He is seeking the New Creation and not this old creation.
“ Yea doubtless, and I count all things but loss for the excellency of the knowledge of Christ Jesus my Lord: for whom I have suffered the loss of all things, and do count them but dung, that I may win Christ,
 And be found in him, not having mine own righteousness, which is of the law, but that which is through the faith of Christ, the righteousness which is of God by faith:
 That I may know him, and the power of his resurrection, and the fellowship of his sufferings, being made conformable unto his death;
 If by any means I might attain unto the resurrection of the dead.
 Not as though I had already attained, either were already perfect: but I follow after, if that I may apprehend that for which also I am apprehended of Christ Jesus.
 Brethren, I count not myself to have apprehended: but this one thing I do, forgetting those things which are behind, and reaching forth unto those things which are before,
 I press toward the mark for the prize of the high calling of God in Christ Jesus.” Phil. 3:8-14
A Christian is to seek the Lord Jesus Christ each day of his or her life. He is to live in the presence of God as he goes about his day to day life. A Christian is to always have the Lord before him as he goes through all the stages of life-youth, middle age, and old age-school, work, family and retirement. We are here only for a moment and we must be preparing ourselves for Heaven/the age to come.
As a Christian we can get caught up in the affairs of this world. We can lose sight of the goal of this life, which is glorification.
“ And so it is written, The first man Adam was made a living soul; the last Adam was made a quickening spirit.
 Howbeit that was not first which is spiritual, but that which is natural; and afterward that which is spiritual.
 The first man is of the earth, earthy: the second man is the Lord from heaven.
 As is the earthy, such are they also that are earthy: and as is the heavenly, such are they also that are heavenly.
 And as we have borne the image of the earthy, we shall also bear the image of the heavenly.
 Now this I say, brethren, that flesh and blood cannot inherit the kingdom of God; neither doth corruption inherit incorruption.
 Behold, I shew you a mystery; We shall not all sleep, but we shall all be changed,
 In a moment, in the twinkling of an eye, at the last trump: for the trumpet shall sound, and the dead shall be raised incorruptible, and we shall be changed.
 For this corruptible must put on incorruption, and this mortal must put on immortality.
 So when this corruptible shall have put on incorruption, and this mortal shall have put on immortality, then shall be brought to pass the saying that is written, Death is swallowed up in victory.
 O death, where is thy sting? O grave, where is thy victory?
 The sting of death is sin; and the strength of sin is the law.
 But thanks be to God, which giveth us the victory through our Lord Jesus Christ.
 Therefore, my beloved brethren, be ye stedfast, unmoveable, always abounding in the work of the Lord, forasmuch as ye know that your labour is not in vain in the Lord.” First Corinthians 15:45-58
What is going on in the world right now is stated in First Peter chapter 2-
“ Wherefore laying aside all malice, and all guile, and hypocrisies, and envies, and all evil speakings,
 As newborn babes, desire the sincere milk of the word, that ye may grow thereby:
 If so be ye have tasted that the Lord is gracious.
 To whom coming, as unto a living stone, disallowed indeed of men, but chosen of God, and precious,
 Ye also, as lively stones, are built up a spiritual house, an holy priesthood, to offer up spiritual sacrifices, acceptable to God by Jesus Christ.
 Wherefore also it is contained in the scripture, Behold, I lay in Sion a chief corner stone, elect, precious: and he that believeth on him shall not be confounded.
 Unto you therefore which believe he is precious: but unto them which be disobedient, the stone which the builders disallowed, the same is made the head of the corner,
 And a stone of stumbling, and a rock of offence, even to them which stumble at the word, being disobedient: whereunto also they were appointed.
 But ye are a chosen generation, a royal priesthood, an holy nation, a peculiar people; that ye should shew forth the praises of him who hath called you out of darkness into his marvellous light:
 Which in time past were not a people, but are now the people of God: which had not obtained mercy, but now have obtained mercy.
 Dearly beloved, I beseech you as strangers and pilgrims, abstain from fleshly lusts, which war against the soul;
 Having your conversation honest among the Gentiles: that, whereas they speak against you as evildoers, they may by your good works, which they shall behold, glorify God in the day of visitation.” First Peter 2:1-12
The Lord Jesus is gathering His people and building His Church. What is important right now is that we make sure we belong to the people of God/that we are members of the Church the Body of Christ. “And came and preached peace to you which were afar off, and to them that were nigh. For through him we both have access by one Spirit unto the Father. Now therefore ye are no more strangers and foreigners, but fellow-citizens with the saints, and of the household of God; And are built upon the foundation of the apostles and prophets, Jesus Christ himself being the chief corner stone; In whom all the building fitly framed together groweth unto an holy temple in the Lord: In whom ye are also builded together for an habitation of God through the Spirit” Ephesians 2:17-22
