Lifestyle: In Ephesians 4:25-32, Paul covers a lot of topics:
Therefore, having put away falsehood, let each one of you speak the truth with his neighbor, for we are members one of another [honesty]. Be angry and do not sin [righteous anger]; do not let the sun go down on your anger, and give no opportunity to the devil [sinful anger]. Let the thief no longer steal [theft], but rather let him labor, doing honest work with his own hands [integrity], so that he may have something to share with anyone in need [work]. Let no corrupting talk come out of your mouths [communications], but only such as is good for building up, as fits the occasion, that it may give grace to those who hear [relationships]. And do not grieve the Holy Spirit of God, by whom you were sealed for the day of redemption. Let all bitterness and wrath and anger and clamor and slander be put away from you [bitterness, anger, slander], along with all malice. Be kind to one another, tenderhearted, forgiving one another [kindness, love, forgiveness], as God in Christ forgave you.
Distinction: Most religions—Islam, Confucianism, Judaism, Buddhism—say that it is wrong to steal and lie, that a healthy anger is good, that our work should be honest, that our communications and relationships are important, that we should pursue kindness, love, and forgiveness. Is there any distinctiveness, then, in Christian ethics?
Heart: Paul tells the Ephesians to “put off your old self” and “put on the new self.” Tim Keller comments, “To put off the old self means to live an examined life. You look at every part of your life and ask, ‘Is this what Jesus wants?’”  In reply, however, we find an astounding answer—Jesus wants our hearts. Jesus once said that the Pharisees were “whitewashed tombs” because they were clean on the outside and dead on the inside.  As Keller says, “[Christian] righteousness is not simply a matter of external behavior, but is essentially a matter of the mind, the imagination, the attitudes, and the motives. Apart from this, morality is repression—cold and artificial.”
Prayer: Lord, When we read your commands that target our sanctification, may we never separate our actions from our hearts. Ultimately, you want our hearts. Awaken an affection for Jesus within us this morning so that we obey out of love. Amen.
