For I say, through the grace given unto me, to every man that is among you, not to think of himself more highly than he ought to think; but to think soberly, according as God hath dealt to every man the measure of faith. God has dealt to his children a measure of faith and Jesus revealed that someday there will be an accounting for this. In the parable of the talents the Lord was displeased with the servant with one talent who failed to increase it with usury. With all the prohibitions against usury in the bible the only way this makes sense is if the talent or money represents faith. Money is the currency of the world. Works are often the currency of the church. Faith is the currency of heaven where God does require us to strengthen and increase our faith. The best way I have discovered to increase our faith is by prayer, bible study and fellowship with others who have faith. Faith is contagious so if we surround ourselves with the faithful it is bound to rub off eventually. Unfortunately the opposite is also true where if we surround ourselves with unbelievers their unbelief will rub off on us as well. Also understanding the true place of works in the gospel will strengthen our faith.
