It is the light that SEARCHES the inward parts of the sinner's heart and exposes the sins and the sin that are there. And that light is Christ. He was "the true Light which lighteth every man that comes into the world" (v. 9).
The sinner whose heart is searched cries out for one to SAVE him, and there is but One who can do that. He is "the Lamb of God which takes away the sin of the world" (v. 29).
The sinner who is searched and saved becomes the cherished possession of His Saviour, and that there might be no doubt about it he is SEALED by the Holy Ghost. "The same is He that baptiseth with the Holy Ghost" (v. 33).
Nothing will SATISFY the heart of the one who is searched, saved and sealed, but the company of his Saviour. The question which springs from the heart to the lips is, "Master, where dwellest Thou?" and He answers, "Come and see" (vv. 38-39).
The one who is searched, saved, sealed and satisfied delights to SERVE the One who has blessed him. and he does it spontaneously and successfully constrained by the love that surpasses knowledge. "One of the two which heard John speak, and followed him, was Andrew, Simon Peter's brother, He first findeth his own brother Simon … and he brought him to Jesus" (vv. 40-42).
Thus does He, who created the worlds, bless us. He became flesh in order to do it, and He dwelt among men to reveal the love that was in His heart. He delights to draw men out of the darkness of their ignorance and sin into the light of the love of God. He delights to lift and remove the burden of sin from their souls and bring them to rest and rejoice with Him in His own dwelling place, His Father's love; having given them the Holy Spirit to be the power and the capacity to enjoy that love. And He delights to see them go forth to serve Him, the Holy Spirit being the power for this, Christ Himself being the satisfying centre from which they go, to bring back to Him weary, needy sinners.
Let no Christian stop short of any of these steps in blessing; he will spoil his life if he does; he will lose the fullness of the blessing that may be his, and he will rob his Saviour of His full delight in him. The fact is that the Lord will be satisfied with nothing less than the complete possession of every life that He has redeemed, and He has this in those whom He has searched, saved, satisfied, and whom He can trust with His service.
