The Scriptures thought us that “after we believe” we are, or maybe, sealed with the Holy Spirit of promise, and that this sealing is the earnest of our salvation. Ephesians 1:13, 14: “In whom ye also trusted after that ye heard the word of truth, the gospel of your salvation; in whom also after that ye believed, ye were sealed with the Holy Spirit of promise, which is the earnest of our inheritance until the redemption of the purchased possession, unto the praise of His glory.” This sealing, this earnest of our inheritance, is that which renders our salvation sure.
The great mass of sinners is careless, unconvicted. One should not assume their conviction and preparedness to receive Christ. When preachers are eager to urge sinners immediately to accept Christ, is to begin the work of soul-winning at the wrong end. The sinner needs to hear the whole truth of the word. Though in some cases, there may be a conviction in some men, which is already ripe, and the preacher just needs to present Christ, with the hope of His being accepted; but at ordinary times such cases are exceptional.
Wisdom comes only from the Lord. The wisdom from above is the wisdom that strives to win others to Christ. If any man lacks wisdom he can seek the Lord for it. God is ever willing to give us the wisdom that we need.
