Spurgeon was in the fight for truth as England was being overturned by modernism (like America has been today). There is the Spirit of Christ in genuine disciples that betray their love for His body, the church. Christ loves the Church. Disciples have His Spirit, therefore there is some measure of love burning within His children for the things He loves.

Think on these things.

The burdened spirit is a token of true love to God: those who love the Lord Jesus are wounded in his woundings, and vexed with the vexings of his Spirit. When Christ is dishonored his disciples are dishonoured. Those who have a tender heart towards the church can say with Paul, “Who is offended, and I burn not?” The sins of the church of God are the sorrows of all living members of it. This also marks a healthy sensibility, a vital spirituality. Those who are unspiritual care nothing for truth or grace: they look to finances, and numbers, and respectability. Utterly carnal men care for none of these things; and so long as the political aims of Dissenters are progressing, and there is an advance in social position, it is enough for them. But men whose spirits are of God would sooner see the faithful persecuted than see them desert the truth, sooner see churches in the depths of poverty full of holy zeal, than rich churches dead in worldliness. Spiritual men care for the church even when she is in an evil case, and cast down by her adversaries: “thy servants take pleasure in her stones, and favour the dust thereof.” The house of the Lord is to many of us our own house, his family is our family. Unless the Lord Jesus be extolled, and his gospel conquer, we feel that our own personal interests are blighted, and we ourselves are in disgrace. It is no small thing to us: it is our life. (C. H. Spurgeon. “A Sermon for the Time Present”, Lord’s Day Morning, October 30, 1887.)
