Answer:
A. Follow and trust.
Step-by-step explanation:
The Book of Psalms was written by King David and is mostly hymns in praise of God. It contains 150 chapters and is the central part of the whole Bible.
Chapter 23 states "The Lord is my shepherd, I shall not be in want." (NIV) The speaker of the chapter also talks about his trust in the Lord, and how he "will fear no evil." The psalmist uses a metaphor of a sheep being led by a shepherd, who is Christ. And like the flock who trusted and obeyed their master, the psalmist also expresses his trust in the one leading him, Christ.
Thus, the correct answer is option A.
