For I will not venture to speak anything other than what Christ has accomplished.  Romans 15:18

Set your mind on Christ Resurrected as He orchestrates your life.  Christ is positive magnatism, not dull focus on worldly things which introduces negativity and anguish.  Paul is gives you an example.  Apostle Paul points to the dissension between the two groups in his Church (those who took opposing sides about what to eat, drink and the Sabbath) as a dull focus.  

Christ is alive and blessing us.  He aligns your understanding as to what He is doing in God’s will daily as you tune with Him thru prayer, alert living, and heartfelt loving like Jesus.  Speak of Him, careful not to defile.  ‘But the things that come out of a person’s mouth come from the heart, and these defile them. For out of the heart come evil thoughts—murder, adultery, sexual immorality, theft, false testimony, slander.’ (Matthew 15:18)

Speaking anything other than what Christ has and is accomplishing may be deemed false testimony.
