Jamieson, Fausset and Brown on 2 Peter 1:11

11. an entrance--rather as Greek, "the entrance" which ye look for.

ministered--the same verb as in 2Pe 1:5. Minister in your faith virtue and the other graces, so shall there be ministered to you the entrance into that heaven where these graces shine most brightly. The reward of grace hereafter shall correspond to the work of grace here.

abundantly--Greek, "richly." It answers to "abound," 2Pe 1:8. If these graces abound in you, you shall have your entrance into heaven not merely "scarcely" (as he had said, 1Pe 4:18), nor "so as by fire," like one escaping with life after having lost all his goods, but in triumph without "stumbling and falling."
