Evangelism and Discipleship
As we consider the important role truth plays in the evangelistic process, it is worth noting that truth continues to play a central role in discipleship and all areas of ministry, including what we often refer to as spiritual warfare.
The apostle Paul told Timothy that God “desires all men to be saved” (a proper response to the evangelistic process) and “come to the knowledge of the truth” (1 Ti.2:4). As followers of Christ, we are to “be renewed in the spirit of your mind and put on the new self, which in the likeness of God has been created in righteousness and holiness of the truth” (Ep.4:23-24). This is to be an ongoing aspect of our continual growth and transformation. Part of our growth process includes becoming equipped to deal with and stand against “the rulers, against the powers, against the world forces of this darkness, against the spiritual forces of wickedness in the heavenly places” (Ep.4:12). Notice in the following quote that the process begins with truth, seemingly in a defensive capacity, and includes truth, seemingly in an offensive capacity.
It must be emphasized, however, that mere intellectual knowledge of truth is not the goal. Truth is important and instrumental to the process of transformation. Transformation involves active obedience in response to truth. The writer of Hebrews tells us “…if we go on sinning willfully after receiving the knowledge of the truth, there no longer remains a sacrifice for sins…” (Heb.10:26) and that Jesus “…became to all those who obey Him the source of eternal salvation…” (Heb.5:9). Jesus told us that “…everyone who hears these words of Mine and acts on them, may be compared to a wise man who built his house on the rock” (Mt.7:24). However, we must be aware of the fact that the same truth that can set us free when responded to in a proper way can also condemn us if responded to improperly. Consistent with Proverb 10:29 which says, “The way of the LORD is a stronghold to the upright, But ruin to the workers of iniquity,” Jesus states, “Everyone who hears these words of Mine and does not act on them, will be like a foolish man who built his house on the sand” (Mt.7:26).
Truth, and a proper response to it, plays a huge part in God’s government over moral agents.
 Evangelism involves using truth to convert sinners, to promote a change of heart.
 Discipleship involves using truth to instruct and equip converts in the Christian lifestyle and ministry.
 “So Jesus was saying to those Jews who had believed Him, ‘If you continue in My word, then you are truly disciples of Mine; and you will know the truth, and the truth will make you free.'” (Jn.8:31-32)
 “The sum of Your word is truth, and every one of Your righteous ordinances is everlasting” (Ps.119:160).
“Sanctify them in the truth; Your word is truth” (Jn.17:17).
