Philippians 1:21

“For to me to live is Christ, etc.] Christ was his life “efficiently”, the efficient cause and author of his spiritual life; he spoke it into him, produced it in him, and disciplined him with it: and he was his life, objectively, the matter and object of his life, that on which he lived; yea, it was not so much he that lived, as Christ that lived in him; he lived by faith on Christ, and his spiritual life was maintained and supported by feeding on him as the bread of life: and he was his life, “finally”, the end of his life; what he aimed at throughout the whole course of his life was the glory of Christ, the good of his church and people, the spread of his Gospel, the honour of his name, and…”

His aim was not honor, learning, gold, pleasure; it was, to glorify the Lord Jesus. This was the single purpose of his soul - a purpose to which he devoted himself with as much singleness and ardor as ever did a miser to the pursuit of gold, or a devotee of pleasure to amusement, or an aspirant for fame to ambition. This implied the following things: (1) A purpose to know as much of Christ as it was possible to know - to become as fully acquainted as he could with his rank, his character, his plans, with the relations which…”

“To me to live is Christ - To know, to love, to follow Christ, is my life, my glory, my joy. Philippians 1:22”

“1:21 dying is even better: For believers, death holds no fear, as death leads directly into the presence of Christ (see 1:23; cp. John 5:24; 11:25-26; Rom 8:38-39).”

“to live: Phi 1:20, Phi 2:21; Co1 1:30; Gal 6:14; Col 3:4 to die: Phi 1:23; Isa 57:1, Isa 57:2; Rom 8:35-39; Co1 3:22; Co2 5:1, Co2 5:6, Co2 5:8; Th1 4:13-15; Rev 14:13 Philippians 1:22”
