1 Chronicles 12:1
Here is an account of those who appeared and acted as David's friends, while he was persecuted. No difficulties or dangers should keep the sinner from coming to the Savior, nor drive the believer from the path of duty. Those who break through, and overcome in these attempts, will find abundant recompence. From the words of Amasai we may learn how to testify our affection and allegiance to the Lord Jesus; his we must be throughly; on his side we must be forward to appear and act. If we are under the influence of the Spirit, we shall desire to have our lot among them, and to declare ourselves on their side; if in faith and love we embrace the cause of Christ, he will receive, employ, and advance us.
1 Chronicles 12:23
When the throne of Christ is set up in a soul, there is, or ought to be, great joy in that soul; and provision is made, not as here, for a few days, but for the whole life, and for eternity. Happy are those who wisely perceive it to be their duty and interest, to submit to the Saviour Jesus Christ, the Son of David; who renounce for his sake all that is not consistent; whose earnest endeavours to do good are directed by the wisdom that God giveth, through acquaintance with his word, experience, and observation. If any man lack this wisdom, let him ask it of God, who giveth to all men liberally, and upbraideth not, and it shall be given him.
