It may sound harsh and unloving to some, but the truth of John 15 is bear fruit or be cast into the fire! Bear fruit or be cut off the vine! Bear fruit or be taken away to wither and die! That is radical. Bearing fruit is not an option. It is either fruit or fire!
What kind of fruit is Jesus referring to? I believe one of it is winning souls. When we see the Lord face to face, will our baskets be filled with fruits - the lives of many people whom we have won to Christ?
Jesus asked us to bear fruit and he goes on to say "much fruit," "more fruit." Are you a fruitful Christian?
