Whence comes the nervous, dithery, take-no-risks mood that mars so much of our discipleship?...
One reason, it seems, is that in our heart of hearts we are afraid of the consequence of going the whole way into the Christian life. We shrink from accepting burdens of responsibility for others because we fear we should not have strength to bear them. We shrink from accepting a way of life in which we forfeit material security because we are afraid of being left stranded. We shrink from being meek because we are afraid that if we do not stand up for ourselves we shall be trodden down and victimized, and end up among life's casualties and failures. We shrink from breaking with social conventions in order to serve Christ because we fear that if we did, the established structure of our life would collapse all around us, leaving us without a footing anywhere.
It is these half-conscious fears, this dread of insecurity, rather than any deliberate refusal to face the cost of following Christ, which make us hold back. We feel that the risks of out-and-out discipleship are too great for us to take. In other words we are not persuaded of the adequacy of God to provide for all the needs of those who launch out wholeheartedly on the deep sea of unconventional living in obedience to the call of Christ....This, at bottom seems to be what is wrong with us. We are afraid to go all the way in accepting the authority of God, because of our secret uncertainty as to his adequacy to look after us if we do.
