The Core of Christianity.

Jesus Christ is the core of Christianity. And Christianity is a PRESET way of "rightly" doing the Will of God, which is to save the whole world. 

What do I mean by "preset"? 
According to online dictionary:
-(verb) To set or adjust (a value that controls the operation of a device) in advance of its use. "the water is heated quickly to a preset temperature".
-(noun) A control on electronic equipment or on software that is set or adjusted beforehand to facilitate use.

To Whom it concerns'.
YOU CANNOT CARRY OUT THE WILL OF THE FATHER WITHOUT CHRIST. Anyone that claim to want to save the world and does not regard the Son of God is false. To God, saving the whole world can only be done in one way, and that is through Christ. 

"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." (John 3:16). This is the Will of God for everyone, and it cannot be changed. We are all expected to come to God through Jesus, or to the Father through the Son to be saved. And for those that are saved, we are all mandated and expected to further this great cause. 

Who should comply to the Will of the Father?

EVERYONE BORN OF GOD. To say you are born of God by Water, Blood and Spirit of Christ Jesus and not be compliant, you are nothing but a liar. Who are you to not be compliant?!

1. The Son that was sent said this of Himself, 
"And this is the will of him that sent me, that every one which seeth the Son, and believeth on him, may have everlasting life: and I will raise him up at the last day." (John 6:40). He knew fully well that He (Jesus) is given to the whole world as the Bread of life - He will be "baked and served" to give life to everyone that believes.

2. This is said of all that truly believe in the Son,
"Not every one that saith unto me, Lord, Lord, shall enter into the kingdom of heaven; but he that doeth the will of my Father which is in heaven." (Mat 7:21). IF YOU DO NOT DO THE WILL YOU ARE NOT OF GOD. As a believer, we are expected to "serve the Bread of life" to the whole world. You must SERVE in any capacity you have available to you by all means. 

In conclusion, people must get to know Christ Jesus for themselves to receive the guaranty of eternal life - now and forever. This is what Jesus promise to do to all that come to the Father through Him. He is not waiting to turn anyone down at the last minute, but to make sure all are saved at the very end. The Father is bringing people (i.e, the lost) to Christ to be born-again into Him, and THIS IS THE WILL OF THE FATHER.
