…but as He who called you is holy, you also be holy in all your conduct, because it is written, “Be holy, for I am holy.” – 1 Peter 1:15, 16

Holiness is the most real power that can be possessed by men or women. We may preach orthodoxy, but we must also live orthodoxy. God forbid that we should preach anything else; but it will be all in vain, unless there is a life at the back of the testimony. An unholy preacher may even render truth contemptible. In proportion as any of us draw back from a living and zealous sanctification we shall draw back from the place of power. Our power lies in this word, “Follow Me.” Be Jesus-like. In all things endeavor to think, and speak, and act as Jesus did, and He will make you fishers of men. This will require self-denial. We must daily take up the cross. This may require willingness to give up our reputation-readiness to be thought fools, idiots, and the like, as men are apt to call those who are keeping close to their Master. There must be the cheerful resigning of everything that looks like honor and personal glory, in order that we may be wholly Christ’s, and glorify His name. We must live His life and be ready to die His death, if need be. O brothers, sisters, if we do this and follow Jesus, putting our feet into the footprints of His pierced feet, He will make us fishers of men. If it should so please Him that we should even die without having gathered many souls to the cross, we shall speak from our graves. In some way or other the Lord will make a holy life to be an influential life. It is not possible that a life which can be described as a following of Christ should be an unsuccessful one in the sight of the Most High. “Follow Me,” and there is an “I will” such as God can never draw back from: “Follow Me, and I will make you fishers of men.”

There is something for us to do: we are graciously called to follow Jesus. Holy Spirit, lead us to do it. ~ C.H. Spurgeon
