“If God’s primary purpose for the saved were loving fellowship, He would take believers immediately to heaven, where spiritual fellowship is perfect, unhindered by sin, disharmony, or loneliness. If His primary purpose for the saved were the learning of His Word, He would also take believers immediately to heaven, where His Word is perfectly known and understood. And if God’s primary purpose for the saved were to give Him praise, He would, again, take believers immediately to heaven, where praise is perfect and unending. There is only one reason the Lord allows His Church to remain on earth: to seek and to save the lost, just as Christ’s only reason for coming to earth was to seek and to save the lost. “As the Father has sent Me,” He declared, “I also send you” (John 20:21). Therefore, believers who are not committed to winning the lost for Jesus Christ should reexamine their relationship to the Lord and certainly their divine reason for existence. Fellowship, teaching, and praise are not the mission of the Church but are rather the preparation of the Church to fulfill its mission of winning the lost. And just as in athletics, training should never be confused with or substituted for actually competing in the game, which is the reason for all the training.” John MacArthur
“Christ said, ‘I came into this world for one reason—to reach and save lost souls!’ Yet, this was not only Jesus’ mission. He made it our mission as well: ‘And he said unto them, Go ye into all the world, and preach the gospel to every creature’” (Mark 16:15). David Wilkerson
Luke 19:10 for the Son of Man has come to seek and to save that which was lost.
