Passage
As it is written in the prophets, Behold, I send my messenger before thy face, which shall prepare thy way before thee.
As it is written in the prophets, Behold, I send my messenger before thy face, which shall prepare thy way before thee.
Mark 1:1 The beginning of the gospel of Jesus Christ, the Son of God;
Mark 1:2 As it is written in the prophets, Behold, I send my messenger before thy face, which shall prepare thy way before thee.
Mark 1:3 The voice of one crying in the wilderness, Prepare ye the way of the Lord, make his paths straight.
Mark 1:4 John did baptize in the wilderness, and preach the baptism of repentance for the remission of sins.
The verse centers on "written", "prophets", "behold", "send", "messenger", "before", "face", and "shall". It is saying that the verse draws attention to "written" and "prophets", so its meaning should be read from those terms before moving to application.
The nearby context moves from verse 1's "The beginning of the gospel of Jesus..." into verse 3's "The voice of one crying in the...", so "written" and "prophets" belong inside that flow. In Mark context, the local focus is Christ, faith, and discipleship.
A plain takeaway is to answer the verse's own emphasis on "written" and "prophets" with trust shaped by these words, not by a vague optimism outside the passage.
