I have been crucified with Christ; it is no longer I who live, but Christ lives in me; and the life which I now live in the flesh I live by faith in the Son of God, who loved me and gave Himself for me. -Galatians 2:20

(T)here is an idea in the world that persons ought to be very religious on a Sunday, but it does not matter what they are on a Monday. How many pious preachers are there on a Sabbath-day, who are very impious preachers during the rest of the week! How many are there who come up to the house of God with a solemn countenance, who join the song and profess to pray, yet have neither part nor lot in the matter, but are “in the gall of bitterness and in the bonds of iniquity!”…When should a Christian, then, be like Jesus Christ? Is there a time when he may strip off his regimentals-when the warrior may unbuckle his armor, and become like other men? Oh! no; at all times and in every place let the Christian be what he professes to be. …Aye, we all need the consolations of God at last; but how can we expect to enjoy them unless we obey the precepts of religion during life? My brethren, let me say, be ye like Christ at all times. Imitate Him in public. Most of us live in some sort of publicity; many of us are called to work before our fellow-men every day. We are watched; our words are caught; our lives are examined-taken to pieces. The eagle-eyed, argus-eyed world observes everything we do, and sharp critics are upon us. Let us live the life of Christ in public. Let us take care that we exhibit our Master, and not ourselves-so that we can say, “It is no longer I that live, but Christ that liveth in me.” Take heed that you carry this into the church too, you who are church-members. Be like Christ in the church. How many there are of you like Diotrephes, seeking pre-eminence? How many are trying to have some dignity and power over their fellow Christians, instead of remembering that it is the fundamental rule of all our churches, that there all men are equal-alike brethren, alike to be received as such. Carry out the spirit of Christ, then, in your churches, wherever ye are; let your fellow members say of you, “He has been with Jesus.”~ C.H. Spurgeon
