A sheep that wanders away is in danger:
1. Of becoming lost and dying of hunger and thirst.
2. Of falling and getting mortally hurt.
3. Of being killed by a wolf.
If WE become lost, we can die of hunger. Jesus said that HE is the bread of life, without Him we will die of hunger.
John 6:33-35
33“For the bread of God is that which comes down out of heaven, and gives life to the world.” 34Then they said to Him, “Lord, always give us this bread.”
35Jesus said to them, “I am the bread of life; he who comes to Me will not hunger, and he who believes in Me will never thirst."
We can fall away from God. When we do, we always get hurt, one way or another. God gave us His commandments to keep us safe.
Mathew 24:10-13
10“At that time many will fall away and will betray one another and hate one another. 11“Many false prophets will arise and will mislead many. 12“Because lawlessness is increased, most people’s love will grow cold. 13“But the one who endures to the end, he will be saved. "
We can die because of an unbelieving heart.
Hebrews 3:12-14
12Take care, brethren, that there not be in any one of you an evil, unbelieving heart that falls away from the living God. 13But encourage one another day after day, as long as it is still called “Today,” so that none of you will be hardened by the deceitfulness of sin. 14For we have become partakers of Christ, if we hold fast the beginning of our assurance firm until the end,
