(NIV) Job 5:17 Blessed is the one whom God corrects; so do not despise the discipline of the Almighty.
Anger is a way to correct the one who loves you.. BUT.. sacrifice is the way to correct the ones whom we love..
We come accross anger often in our lives.. starting from childhood.. when we do something wrong mom or dad get angry with us and they punish us.. and sometimes at school when we are not attentive the teacher gets angry at us and she/he punishes us.. at work when ouroutput is not meeting the expectations our boss gets angry with us and they punish us.. and sometimes when we are in these roles we tend to get angry.. this anger serves to be the primary source for making the people who are dependent on us or people over whom we have authority or the people who really love us.. to repentence..
When we look at the old testament we see Spirit of God reveals this anger to ensure that the Israelites follow the commandments and they live a life planned by God for them.
(NIV) Job 36:10 He makes them listen to correction and commands them to repent of their evil.
But when it comes to the people who are rebellious.. like the children in their teens or some students who do not obey the rules or the collegues who are not dedicated in their work.. anger cannot be used as a mechanism to correct them.. it will lead to arguements, hatred, escalations and more chaos.. then when look at what is the best way to correct them.. is to sacrifice for them.. in order to make them understand that we care for them.. that we love them..
Like how Christ died on the Cross to show the people who are rebellious.. His love on the Cross.. so that we believe in His love.. and we surrender to His love.. we leave our hatred and walk into His saving grace..
(NIV) Romans 5:8 But God demonstrates his own love for us in this: While we were still sinners, Christ died for us.
