“We lost everything at once by a single fault of Adam, but in baptism God does not give us back at once all the integrity of the Divine gift. In order that it may be a source of merit because of the effort it calls forth, He leaves us in concupiscence, the source of sin, which tends to diminish or destroy the Divine life. Therefore our whole existence ought to be the realisation of what baptism inaugurates…Grace is the principle of life in us, but it is a germ we must cultivate; it is that kingdom of God within us that Our Lord Himself compares to a grain of mustard seed which becomes a great tree. So it is with the Divine life in us…
“Let us often renew the virtue of this sacrament of adoption and initiation by renewing the promises made in baptism, so that Christ, born in our souls in faith upon that day, may grow more and more in us. That is a very useful practice of piety…stir up in yourselves the grace received at baptism, by renewing the promises then made. For example, when after Communion, while Our Lord is really present in our hearts, we renew with faith and love our dispositions of repentance, of renunciation of Satan, sin and the world, so as to attach ourselves only to Christ and His Church, then the grace of baptism springs up from the depth of our souls, where the character of baptism remains indelibly engraved. And this grace produces, through the virtue of Christ, Who dwells in us with His Spirit, as it were a new death to sin, a new inflowing of Divine life, a new intensity of union with Jesus Christ.” ~Bl. Columba Marmion, OSB; Christ, the Life of the Soul
