I cannot tell you how many times I will be in the middle of something and one of my children just walk up talking to me, as if I was just sitting there waiting for them to walk up and need something from me. It drives me BANANAS. Why? Because it is really selfish- as if the whole world is here waiting patiently for that child's next move. It says, "What I need/want is THE most important thing under Heaven, so I am going to force you to hear me RIGHT NOW while it is convenient for ME."
Today (during my Thursday walk with my Sista-friends), one of my sista-friends said, "We have to learn to not barge in on God." I immediately had a picture of God (bare with me) sitting at His big desk in the sky (stay with me) and me just barging in whenever it is convenient with whatever want/need/request/or affection I NEED to tell Him at whatever moment. How RUDE! It happens though.
Now, we can talk to God at any time and all day long, but OH what sweet time in prayer it is when we approach him with the respect and honor He so richly deserves. We need to come to God humbly, seeking His attention in His time and at His will. We should spend time in honor of him, praising Him, long before we give him our wish list of wants/needs. Our hearts should be bent towards the goal of leaving time with the Lord knowing that we honored Him during that time more than just completed a task.
I obviously cannot speak for the Lord, but I know when my children barge in on me I have a VERY difficult time even listening to them at all. Usually, they get sent back to where they came with instructions to try again later. YIKES!
