The seeds of contemplation and sanctity have been planted in those souls, (all people of good will)but they merely lie dormant. They do not grow. In other words: sanctifying grace occupies the substance of their souls but never flows out to inflame and irrigate and take possession of their faculties, their intellect and will. God will not manifest himself to these souls because they do not seek him.
Merton’s wisdom tells us that we can only achieve true unity with God when we seek it with our whole beings. God has implanted within each of us the seeds that will bring us to full fellowship with Him, but it is our mission to brings forth the fruit offered by these seeds. His grace is a gift that gives each one the capacity to fully possess the salvation of God.
Our desire to see ourselves fully sanctified with our creator is the lifelong mission of the Christian. Many a person has gone through life, many times a good life, without fully claiming the wonderful grace of God. Merton warns that Christian growth is a proactive venture, because God does not force Himself upon us. We are called to seek and desire Him.
