Matthew Henry Commentary Philippians 4:1

"Wherefore, my brethren beloved and longed for, my joy and crown, so stand fast in the Lord, my beloved." — Philippians 4:1 (ASV)

The believing hope and prospect of eternal life should make us steady and constant in our Christian course. There are differences in gifts and graces, yet, being renewed by the same Spirit, we are brothers and sisters. To stand fast in the Lord is to stand fast in his strength and by his grace.
