Put Away Lying
Therefore, putting away lying, "Let each one of you speak truth with his neighbor," for we are members of one another.
Because you are a Christian, your life ought to be permeated with truth. When you were born again, God put the Spirit of truth in you (John 16:13). The Spirit’s role is to guide you into all truth. The Spirit wants to fill your mind with whatever is true (Phil. 4:8). If you allow the Spirit to fill you with God’s truth, you will be truthful in your actions and in your relationships. According to Jesus, this means that your yes will always be yes, and your no will always mean no (Matt. 5:33–37).
The world considers truth optional. Deception permeates every corner of society because the prince of this world is the author and father of lies (John 8:44). From his first contact with people, Satan has been lying to them and persuading them to live in falsehood rather than in truth.
The world will tempt you to compromise the truth. You may be fooled into thinking that you can accomplish greater good by withholding the truth. That is a demonic deception. You cannot use deception to build the kingdom of God! God refuses to use sinful means to accomplish His holy purposes. You may be tempted to live a lie by projecting a false image of yourself. Jesus condemned this as hypocrisy (Luke 12:56). When you sin, you will be tempted to conceal the truth; yet only as you confess the truth will you be forgiven and set free (James 5:16).
What you say reflects what is in your heart (Matt. 12:34). If your heart is filled with deception, your mouth will speak falsehood. Ask God to permeate you with His truth so that you find falsehood, in any form, abhorrent.
