Set your mind on the things above, not on the things that are on earth.
It has been said that you can not control the wind but you can set the sails. As human beings we can not control all the events that blow our way but we can decide how we will respond to them. As Christians we are encouraged to set our minds on things above and not on earthly things. Well, that is a little hard to do sometimes but you can develope a "mindset". Try to see things from God's perspective and not through your limited vision. A perfect example is David and Goliath. From a human perspective Goliath looked very frightening indeed, but David saw him through God's eayes and he did not look so big then. Whatever you are facing try to set your mind on a heavenly perspective. Consider God's vantage point and then ask Him to help you deal with the day to day Giants
