Jesus Christ the same yesterday, and today, and forever.  Hebrews 13:8.
Jesucristo es el mismo ayer, y hoy, y por los siglos.  Hebreos 13:6.
This profound statement is very simple to understand. 
It says that what Jesus did, He will still do!! 
He still heals,  He still works miracles,  He is still calling us to repentance and holiness, and He is still setting the captives free!! 

"Not by might, nor by power, but by MY Spirit, says the Lord of Hosts."
Zechariah 4:6.

"Behold the Lord's hand is not shortened that it cannot save, neither His ear heavy that it cannot hear."  Isaiah 59:1.
