Everything that a man leans upon but God, will be a dart that will certainly pierce his heart through and through.

Ah! how many in these days have lost their estates, their friends, their lives, their souls, by leaning upon their admired parts and abilities! The saints are described by their leaning upon their beloved, the Lord Jesus (Cant. 8:5).

He that leans only upon the bosom of Christ, lives the highest, choicest, safest, and sweetest life.

Miseries always lie at that man’s door that leans upon anything below the precious bosom of Christ; such a man is most in danger, and this is none of his least plagues, that he thinks himself secure. It is the greatest wisdom in the world to take the wise man’s counsel:

“Trust in the Lord with all thine heart, and lean not to thine own understanding” (Prov 3:5).
