in simplicity of heart
The soul is like hardening clay
if it clings to materiality
and like soft wax when it clings to God
Saint Maximos the Confessor
Therefore the Christian, who is called to a heavenly country, who is only a stranger and a sojourner upon earth, ought not attach his heart to anything earthly, but should cling to God alone, the Source of life, our resurrection, and the Life eternal.
St John of Kronstadt
My Life in Christ
