For this is the love of God, that we keep his commandments: and his commandments are not grievous.
This is - the love of God consists in this.
Not grievous - as many think them. It is 'the way of the transgressor' that "is hard" (Proverbs 13:15). What makes them to the regenerate "not grievous" is faith (1 John 5:4). In proportion as faith is strong, the grievousness of God's commandments to the rebellious flesh is 'overcome.' The reason why believers feel any irksomeness in God's commandments is, they do not realize fully by faith their spiritual privileges.
