As followers of Christ we are to put off the Old self and put on the New self. In Ephesians 4:25 Paul begins a series of practical teachings to explain how to put off the "old" and put on the "new." He starts with teaching the church to put off Falsehood and speak Truth. There is more to falsehood than just lying and speaking the Truth is more than just not lying. Jesus is the Truth and we must proclaim truth to our neighbor. What's our motivation for putting off falsehood and speaking the truth? "For we are members one of another."
