Faith

Caleb's faith in Joshua 14 is a great picture of Biblical faith: acting upon the Word of God. Caleb keeps referring back to what the LORD had said/promised and claiming those promises. Dale Ralph Davis:

Sometimes we place our faith in faith; that is, we believe that if we have enough faith we will be able to weather the storm. We forget that great faith is not so necessary as genuine faith (Luke 17.5-6). The object of faith, by definition, is God (not faith). 'It is not so much great faith in God that is required as faith in a great God' [Leon Morris]. If we are Caleb's disciples we will take the promises of God, turn them into prayers, and plead them back to God...I must not trust how spiritual I feel but what has gone forth from God's sacred mouth.

Faith is always looking into the past, seeing God's goodness there, dragging it into the present, pondering it, praising for it, and so going on from strength to strength. The perspective of faith takes in God's goodness, responds in gratitiude, and finds grace for God's next call.
