<p>4:26 <i>In your anger, do not sin Do not let the sun set while you remain angry</i>- This is in the context of appealing for unity between the members of the Lord's body (:25). Unresolved anger with other limbs of the body is a sure way to stop that body functioning. Anger in itself is a purely natural reaction, and is seen in both God and His Son. The issue is, how to &quot;be angry and sin not&quot; (Eph. 4:26)? God &quot;made a path for His anger&quot; with Egypt, by bringing plagues upon them and slaying their firstborn (Ps. 78:50 RV). Anger has to go somewhere, for otherwise it burns within us and rises up ultimately into extremely damaging and inappropriate forms of behaviour. I say 'inappropriate' because pent up anger has a way of bursting forth upon anyone in its way, who may likely be nothing to do with the cause or object of the initial anger. Anger is a form of energy, and as such it must be harnessed. Throughout the Old Testament, we often read of God being &quot;provoked to wrath&quot; by human sin, and His anger burning. There's very little said about this in the New Testament; and I wonder if this is because the ultimate path which God made for His anger was in giving His Son to die for human sin, rather than endlessly seeking to punish human sin and be hurt by it. Immediately let's take an obvious lesson: don't waste your anger energy on endlessly fighting those who provoke you, but use it positively. Throw it in to some project or other for the Lord. For anger is to some extent reflective; whilst we remain horns locked with a situation, both our opponent and ourselves are feeding off each others' anger. Hence the wise advice of Prov. 22:24,25: &quot;with a wrathful man you shall not go: lest you learn his ways&quot;. Disengage from anger situations.</p><p>In any case, we are to seek to not end any day angry. The only way to end the day without anger is to forgive- for if we make our anger dependent upon the repentance or improved behaviour of another party, then we will not be able to stop our anger. The teaching here is clearly that we have power over our own anger, and can cease it if we wish- regardless of the situation or individuals provoking the anger. The quotation &quot;Be angry and sin not&quot; is from Ps. 4:4 LXX- David had anger with Saul and yet rose above it, perhaps by not allowing it to cripple him because David forgave Saul. Psalm 4 continues: &quot;commune with your own heart upon your bed, and be still&quot;. It seems Paul is interpreting that as meaning that we should within ourselves decide to forgive and not be angry, and fall asleep &quot;still&quot; and in peace.</p>
