Mark 4:26-34
The harvest is coming. (Mark 4:26-29)
The parable of the mustard seed.(Mark 4:30-34)
Our Lord began with 12 Apostles. Later, there were as many as 500 believers (1 Cor. 15:6). Peter won 3,000 at Pentecost; and throughout the Book of Acts, that number steadily increased (Acts 4:4; 5:14; 6:1, 7). In spite of the sins and weaknesses of the church, the message has been carried to other nations; and one day, saints from every nation shall worship before His throne (Rev. 5:9).
Verse 33 implies that Mark presented only a small selection of what Jesus taught. The same is true of the other Gospel writers so that no one of them or all of them together give a complete account of everything that Jesus did or taught (cf. John 20:30–31). Again Mark emphasized the necessity of understanding. A better translation of the last part of v. 33 may be “in a way they could understand.”
