Abel, Enoch, Noah, Abraham, Sarah, Isaac, Jacob, Joseph, Moses, Rahab, Gideon, Barak, Jephthae, David, Samuel, the prophets: these are people that lived out a life of faith. We can look to them for courage to continue to fight our good fight of faith. 
If you are struggling find these people in the Word. Look to how they dealt with jealousy, friendship, solitude, responsibility, trust, leadership, unworthiness, obedience, and pressure. God has given their stories to help us as we live out ours. Take advantage of the wisdom at your fingertips.
