Life would be so much better if we would just listen to Yahweh. It isn't like he has just left us on our own. We were never meant to go it alone; it was always his plan for us to be with him in our journey because we need him. If we could understand and accept his wisdom life would be much better for us. Looking at the beginning of things gives us a clear example of this.
Adam and Eve had already rebelled against Yahweh. They had been sent out of the garden and they had started having children. Cain and Abel were the first and their parents raised them well. They knew Yahweh well enough to want to honour him with offerings, but they still had much to learn. Cain's offering wasn't quite up to par, or perhaps it was his attitude. Whatever it was, Yahweh saw something that concerned him and like any good father, he warned Cain:
Cain was mad, not understanding that Yahweh was teaching him something here. Like so many youth, he could only see it from his perspective and refused to learn. Instead, he allowed his emotions to take over and lead him in a direction that would bring a lot of pain and destruction. It is hard when emotions take over. Once we give them authority over us it is almost impossible to reign them in.
Yahweh was very tender and compassionate to Cain, pointing out that sin wanted to have his way with him. Like a good dad he tells him that he has to gain control over this thing and not allow it to dictate to him. Any time we allow emotions to rule over us, we wake up the next day filled with regret. In a fit of anger we say things that should never be said; we do things that should never be done; me make decisions and declare things that only produce bad seed. We may not see the results immediately but those bad seeds are going to produce bad things at some point on our timeline.
Cain could not gain the control of which Yahweh had spoken to him and that emotional sin led to the murder of his brother. It seemed such a trivial thing but it is amazing how small things can escalate into large things when emotions lead us into the path of sin. Thousands of years later we still need to hear the council of Yahweh as he tells us that we should "rule over it".
Jesus has given us freedom and authority over such matters in our life. Anything that comes from the root of sin has lost its power over us because Jesus has freed us from the iron-fist slavery of sin. We are no longer the victim of our emotions. Instead, we have become slaves to his righteousness so that we no longer have an excuse for not ruling over that which once ruled over us. It is only a lack of application and discipline on our part. All we have to do is hear Jesus say, "Go and sin no more", believe he made it possible by giving us his power and authority and walk in the authority he has given us over all such things. Emotions are a wonderful thing but they no longer rule over us when we have given ourselves to Jesus.
