Eli demonstrated a high level casualness in his answer. A casual attitude describes the way you feel or think about things. Collins dictionary describes such as, the way..” you are, or you pretend to be, relaxed and not very concerned about what is happening or what you are doing”. This laid back and easy going state of mind is a classic recipe for lost opportunities. What Samuel told him should have generated a deep sense of remorse and perhaps an immediate call for a family meeting. Apparently Eli had reached a point that he had thrown in the towel. Read that again. How do you feel? Don’t ever get to the point of being casual with God. This casual attitude is what Paul objected to in the Corinthian church about their response to sexual sins( 1Cor.6:18 ). In Mat.18:9, Jesus warns against the consequences of being casual to sin. Jesus’s answer just like Paul’s was a separation with such a person. What happened to Eli? Was he just tired of his evil children, was it just age? His reply was cold. His children were taken out in the same day. Have you rejected an opportunity for repentance before? That is a casual attitude. Today is another day. Seize your opportunity with God. Recommit for seriousness.
And Samuel told him every whit, and hid nothing from him. And he said, It is the LORD: let him do what seemeth him good. 1 Samuel 3:18 KJV
