John 17:14-23 (KJV) I have given them thy word; and the world hath hated them, because they are not of the world, even as I am not of the world.
I pray not that thou shouldest take them out of the world, but that thou shouldest keep them from the evil.
They are not of the world, even as I am not of the world.
Sanctify them through thy truth: thy word is truth.
As thou hast sent me into the world, even so have I also sent them into the world.
And for their sakes I sanctify myself, that they also might be sanctified through the truth.
Neither pray I for these alone, but for them also which shall believe on me through their word;
That they all may be one; as thou, Father, art in me, and I in thee, that they also may be one in us: that the world may believe that thou hast sent me.
And the glory which thou gavest me I have given them; that they may be one, even as we are one:
I in them, and thou in me, that they may be made perfect in one; and that the world may know that thou hast sent me, and hast loved them, as thou hast loved me.

No false representation

Christians are set as light bearers on the way to heaven. They are to reflect to the world the light shining upon them from Christ. Their life and character should be such that through them others will get a right conception of Christ and of His service.
If we do represent Christ, we shall make His service appear attractive, as it really is. Christians who gather up gloom and sadness to their souls, and murmur and complain, are giving to others a false representation of God and the Christian life. They give the impression that God is not pleased to have His children happy, and in this they bear false witness against our heavenly Father.
