Self-examination serves as a tool for man to use to find out who and what he is. Though some preachers suggest that believers should never question their own salvation experience, the scripture encourages self-examination. If there are doubts, believers should certainly ask questions concerning the basis for their salvation. Was it based upon one’s feelings or solely upon the scriptures? They should ask what they did in order to be saved. Did they join a church, do some penitent work, or did they call upon the name of the Lord Jesus Christ by faith as dictated by the scriptures? They should ask about the effects of their salvation. Have they seen a change of heart, or are they the same that they were before trusting Christ as Saviour?
The Devil was created perfect in every aspect (Ezekiel 28:15) with complete capacity to do right. Yet, he was also created with a free will to choose whether to do right or to do wrong. Sometime in the distant past, he chose to abide “not in the truth.” This conscious decision to depart from the truth caused him to become the “father” of lies. In one form or another, every lie traces back to the work of the Devil. As the enemy of God, Satan wants to deceive God’s creation into believing a lie so that rejecting the truth and remaining condemned in darkness (2 Corinthians 4:4) seems like the natural thing to do. Satan incorporates every deceptive means at his disposal. One of his main tactics is to convince people that there are many ways to heaven (good works, baptism, church membership, etc.) and many ways to know the truth (feelings, science, circumstances, etc.). Yet, the Bible emphatically proves that God is truth and His word is truth and only through God and His word are we assured of learning and knowing truth.
