God's people are compared to sheep quite often in the Scriptures.
Know ye that the LORD he is God: it is he that hath made us, and not we ourselves; we are his people, and the sheep of his pasture. -Psalms 100:3
I have gone astray like a lost sheep; seek thy servant; for I do not forget thy commandments. -Psalms 119:176
Behold, I send you forth as sheep in the midst of wolves: be ye therefore wise as serpents, and harmless as doves. -Matthew 10:16
All we like sheep have gone astray; we have turned every one to his own way; and the LORD hath laid on him the iniquity of us all. -Isaiah 53:6
The Lord Jesus said: "I am the good shepherd: the good shepherd giveth his life for the sheep." - John 10:11
- Follow the leader
Sheep have a strong instinct to follow the sheep in front of them. When one sheep decides to go somewhere, the rest of the flock usually follows, even if it is not a good "decision." For example, sheep will follow each other to slaughter. If one sheep jumps over a cliff, the others are likely to follow. Even from birth, lambs are conditioned to follow the older members of the flock. This instinct is "hard-wired" into sheep. It's not something they "think" about.
We rather have that tendency to follow others too, don't we? God warns us about it.
Thou shalt not follow a multitude to do evil; neither shalt thou speak in a cause to decline after many to wrest judgment: - Exodus 23:2
Sheep are lowly creatures. Yet think of how our Almighty Lord has humbled Himself in being called the "Lamb of God". We are to be like our Lord in all lowliness and meekness. "Take my yoke upon you, and learn of me; for I am meek and lowly in heart: and ye shall find rest unto your souls." -Matthew 11:29
He was oppressed, and he was afflicted, yet he opened not his mouth: he is brought as a lamb to the slaughter, and as a sheep before her shearers is dumb, so he openeth not his mouth. -Isaiah 53:7
But made himself of no reputation, and took upon him the form of a servant, and was made in the likeness of men: And being found in fashion as a man, he humbled himself, and became obedient unto death, even the death of the cross. Wherefore God also hath highly exalted him, and given him a name which is above every name: That at the name of Jesus every knee should bow, of things in heaven, and things in earth, and things under the earth; - Philippians 2:7-10

The next day John seeth Jesus coming unto him,
and saith, Behold the Lamb of God, which taketh
away the sin of the world. -John 1:29
