St. Nikolai Velimirovich –
“The horse is prepared against the day of battle: but salvation is in the Lord” (Proverbs 21:31).
We are obligated to prepare ourselves but our success depends on God. All of our preparation is only a proposal to God but the proposal does not decide, but God decides. That is why people wisely say according to their experience: man proposes and God disposes. O Soldier of Christ, prepare your mind as a good horse, arm your heart with virtues, temper your will with mortifications, but know – that “salvation is in the Lord.”
O Merchant of Christ, practice good trade every day, exchanging the material for the spiritual, the earthly for the heavenly and mortality for immortality, but know – that “salvation is in the Lord.”
O Plowman of Christ, plow and re-plow your soul, sow the good evangelical seed on it every day, weed out the field of your soul from weeds, watch over it, but know that “salvation is in the Lord.”
