In every relationship in your life there will be a gap at times between what you expect of someone and what you actually experience from them. It happens in marriage all the time, doesn't it? I expect my spouse to do this but that’s not what I experience creating a gap. It happens at work. It happens with your kids. It happens with friends. When there's a gap that occurs between what you expect of someone and what you experience from them you will always fill the gap and what you fill the gap with will determine how you respond. If you fill the gap with suspicion, false assumption and trying to guess someone’s motives you will respond negatively. If you fill that gap with trust and a mind-set that says, “I'm going to give them the benefit of the doubt,” then you'll react lovingly.
The same thing is true in your relationship with God. There are times in your walk with the Lord that what you expect of God doesn't match what you experience and there's a gap. It's easy to fill that gap with suspicion and become angry at God rather than filling the gap with trust saying, “You didn't do it the way I wanted You to but I'm going to trust You God because You know best.
