Saint Paul reminds us: You are bought with a great price; glorify and bear God in your body. If we have an hearty and simple desire to do this, the result will be an unfailing and increasing happiness which nothing should disturb. There is no real happiness in this life where there is not a peaceful heart, and God tells us, there is no peace to the wicked. Even religious and devout people, who only half give themselves up to God and retain much self-will, only feebly realise this peace of God. They are easily disturbed by many things; by scruples, by dread of God's judgment, and by the changes and chances of life in this varying world. But he who gives himself unreservedly and submissively to God, will be more and more filled with His peace. Much peace have they that love Thy law, and to them there is no stumbling-block. And as we are prone to grow like to that to which we are closely united, the closer we cleave to God, the stronger, the more steadfast, and the more tranquil shall we become. They who cleave to this world are for ever tossed about with the waves and storms of uncertainty and insecurity. God alone is immovable, unchangeable, and whoso trusts in Him shall not be confounded.
