These days we are bombarded with relentless advertisements telling us, "you deserve... Or you owe it to yourself...." This is the entitlement attitude and it is self-seeking and centered. The entitlement attitude is is pursuing our own agenda without thinking of others or God, or just thinking that God owes me something.
God owes me nothing.
In fact, what we deserve from God is death and hell!
The wages of sin are death. Romans 6:23
God doesn't owe us comfort, abundance, or a perfect life without problems. He gives because he wants to, not because he has to. He is the center and all things exist for his pleasure. What he gives is grace through his unconditional love. In John 1:12, it says the only thing we ARE entitled to through faith in Jesus to forgive and save us, is to be called children of God. Wow! Think about it--he claims me--little ol' me. But, it's what we do with that one entitlement that determines whether we have an entitlement attitude or a servant's heart.
So, our response should be "Here I am, Lord, your servant is listening," just as Samuel replied.
