Instead of complaining at his lot, a contented man is thankful that his condition and circumstances are no worse than they are. Instead of greedily desiring something more than the supply of his present need, he rejoices that God still cares for him. Such an one is "content" with such as he has (Heb. 13:5).
Arthur W. PinkHow does God save His people from the pleasure of sin? The answer is, “By imparting to them a nature which hates evil and loves holiness.” This takes place when they are born again, so that actual salvation begins with regeneration. Of course it does; where else could it commence? Fallen man can neither perceive his desperate need of salvation, nor come to Christ for it, till he has been renewed by the Holy Spirit.
