It is when we have our 'mountaintop' experiences that we feel most alive. It is not necessarily when we feel that God is most with us. Many times when we feel we are at the top of the world, we think we made it all happen and fail to give God the glory. We often say: "look at me! look at what I did! I'm so great!" When all along He allowed us to shine, and the shine should have glorified Him and not us. We need to learn to be humble in these situations.
Why don't most of us feel the presence of God when we are at these extremes? Why do we most feel His presence when we are on level ground and in our safe places. Being on a mountaintop, while it feels great to us is not what it is all about. God wants us to be full of life all the time.
John 10:10.....and He is come that we may have life, and have it more abundantly.
Savor the mountaintop experiences, look around, enjoy the scenery, but remember the One that put you there!
