As Christians, we find complete sufficiency in Christ and His provisions for our needs. There’s no such thing as an incomplete or deficient Christian. Our Savior’s divine power has granted to us everything pertaining to life and godliness. Human wisdom offers nothing to augment that. Every Christian receives all he and she needs at the moment of salvation. Each one must grow and mature, but no necessary resource is missing. There’s no need to search for something more.
John MacArthur
