"Repentance and conversion are not milestones which we pass on the way of life and never see again. This would be to misconceive their true meaning. It is true that life is like a journey ... , but there are abiding principles which are essential for the whole journey and not simply for its commencement. Certainly, repentance has a beginning and comes to a special maturity when we see our need for forgiveness and for union with Christ and the Lord God. But, the fruits of repentance appear at all seasons of life, and keep us in a humble attachment to God. Moreover, when sin appears in our discipleship - and there is no disciple who does not sin - the wells of repentance spring up again as we make confession to God and seek His face. It is for this reason that "Forgive us our trespasses" appears in the Lord's pattern prayer.
Similarly conversion is not a once and for all decision. It is a turning and returning to God throughout our lives. We take up our cross at the beginning, and we have to take it up every day. Constantly we have to take our bearings afresh, like mariners at sea, and correct our course towards God:
"I thought on my ways, And turned my feet unto thy testimonies." (Psalm 119:59)
The threads of repentance and conversion are continuous in the wondrous pattern of life."
