We must have a consciousness of what exactly we are living for every day in this world because one coming day this heaven and earth will pass away (Matthew 24:35).
“For God so loved the world, that he gave his only begotten Son, that whosoever believeth in him should not perish, but have everlasting life. For God sent not his Son into the world to condemn the world; but that the world through him might be saved” (John 3:16-17).
Jesus, the only only begotten Son of God says: “I am the light of the world: he that followeth me shall not walk in darkness, but shall have the light of life” (John 8:12).
“As long as I am in the world, I am the light of the world” (John 9:5).
“I am with you alway, even unto the end of the world. Amen” (Matthew 28:20).
