"This I say therefore, and testify in the Lord, that ye henceforth walk not as other Gentiles walk, in the vanity of their mind, Having the understanding darkened, being alienated from the life of God through the ignorance that is in them, because of the blindness of their heart." (Ephesians 4:17-18 [KJV])
The Bible highlights the plight of the unbeliever. He is in spiritual darkness and is alienated; that is, cut off from the life of God. Ephesians 2:3 further refers to them as children of wrath. That means children appointed unto the wrath or anger of God. What a terrible state for anyone to be!
This should make you think about your friends, relatives, colleagues, neighbours and associates that aren’t born again. They're hopeless in the world, without Christ. You can’t afford to let them keep living without God, drifting farther and farther into the abyss of darkness.
Let the hopelessness of their situation compel you to intercede for them. You may be the only one with the opportunity to touch their lives with the Gospel. Therefore, preach to them and teach them the Word. Contribute your time, effort and resources to soul-winning. Be known for your passion for the Lord, His Gospel and the souls of men.
