What if fish were to leave the water thinking it is restrictive or they feel a curiosity for the world outside of the water? Yes, they would die. What about people who leave the church to live the way they want saying it's too hard to live according to the Word of God? Do they feel free and happy? Just as fish can maintain their lives in the water and freely swim, Christians can be under God's protection and enjoy the blessing of eternal life and freedom only when they live in the Word of God.
"And you will know the truth, and the truth will make you free" (John 8:32).
