2 Timothy 2:4

No one engaged in warfare entangles himself with the affairs of this life, that he may please him who enlisted him as a soldier.  

Whether we are aware of it or not, there is a war going on to keep us from completing our walk of faith.  The closer we walk to God, the more we show what life can be like for the unsaved.  The affairs of life try to come in and choke out the word and make us lose our focus.  We are a soldier in the army of God and will not lose our focus.
