The thief comes only in order to steal and kill and destroy. I came that they may have and enjoy life, and have it in abundance (to the full, till it overflows).
We know God is not a thief, so anything that involves stealing, killing, or destroying is not from God but from the thief himself, satan. It is interesting to note that this verse in it’s context if you read the previous nine verses here, you find out Jesus begins by teaching us that any shepherd who did not come through the door (which He tells us He is that door) is a thief. Jesus, according to Ephesians 4, is the One who gives us the five fold ministries gifts, which includes the pastor (shepherd). What Jesus is teaching us is that any pastor not gifted (called) by Him is a thief. This is the primary way satan steals, kills, and destroys through false doctrine and deceptive teaching. Paul called them teachers who would tickle one’s itching ears. So if we don’t want to be taken advantage of and we want to experience the abundant life God has for us, we need a shepherd who will teach us as Paul also said, “the whole counsel of God.” Beware of having your ears tickled and only hearing what you want to hear but not receiving all of scripture, for when you receive the truth it will set you free to enjoy life to the full.
