Trust in the Lord

Ruth showed herself as worthy to be one of His progenitors as the Virgin Mary was to be His mother. See the notes on Matt. i. 1-16 2.

We should carefully attend to the leadings and to the workings of God's providence; it is our duty and our interest to do both, for the path of duty is ever the way of safety.

Had not Ruth acted thus, how dreary and uncomfortable must her life have been! but she followed God fully, and in a path apparently dangerous, and yet, not only sustained no injury, but succeeded well in all things: from this, as well as from innumerable other circumstances.

Acknowledge him in all thy ways, and he will direct thy steps; and with this we may ever connect, Trust in the Lord with thy whole heart, and lean not to thy own understanding.

Whosoever follows God in simplicity of heart, will most assuredly be guided into all truth.
