Eph 4:25-27, 25 Therefore, putting away lying, “let each one of you speak truth with his neighbor,” for we are members of one another. 26 Be angry, and do not sin”: do not let the sun go down on your wrath, 27 nor give place to the devil.
In the remaining verses, the apostle moves from speaking of general conducts to specifics. As the message is that of unity in the body of Christ, some conducts corrupts and don’t promote unity. For the sake of the old man in comparison to the new man, he uses the words “put off” followed with “put on”. He uses the moral laws (10 commandments) of what to “put off”.
Putting away lying is one of the ten commandments. We are members of one another. All members of one Christian household; hence every member has a right to the truth, we therefore put off lies and put on truth.
In the next verse he encourages that we put off anger that leads to sin. This would partly align with “you shall not murder”, the 6th commandment. Satan works with what is left unattended. Anger at sin is not evil, and there is a place for anger towards injustice, offense, etc. Jesus was angry with those who turned the temple into a marketplace. God is angry with the wicked daily (Psa 7:11). These are righteous angers that if channeled properly would not lead to sin. Anger is one letter short (d) for danger. Be ye angry, and sin not as from Psa 4:4 simply means do not sin through anger is the thought. If circumstances arouse your indignation, do not be led astray. Put off anger and strive for reconciliation.
