"For many deceivers are entered into the world, who confess not that Jesus Christ is come in the flesh. This is a deceiver and an antichrist."" (2 John 7)
Most people wonder why it is so important to understand that Jesus died for us in the flesh.
First, as God, he could not die. Yet He had to die, so that we could live:
"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)
"For Christ also hath once suffered for sins, the just for the unjust, that he might bring us to God, being put to death in the flesh, but quickened by the Spirit." (1 Peter 3: 18)
More importantly, we need the incorruptible blood of an everlasting, perfect man that would cleanse us from all sin, not merely atone for our sins:
"And almost all things are by the law purged with blood; and without shedding of blood is no remission." (Hebrews 9: 22)
"But if we walk in the light, as he is in the light, we have fellowship one with another, and the blood of Jesus Christ his Son cleanseth us from all sin." (1 John 1: 7)
There is real power in that blood, my friend! Wonder working power which keeps on cleansing us!
There are other important reasons for us to understand why Jesus came in the flesh, in the form of a man:
"1There is therefore now no condemnation to them which are in Christ Jesus, who walk not after the flesh, but after the Spirit. 2For the law of the Spirit of life in Christ Jesus hath made me free from the law of sin and death. 3For what the law could not do, in that it was weak through the flesh, God sending his own Son in the likeness of sinful flesh, and for sin, condemned sin in the flesh:" (Romans 8: 1-3)
When Jesus died on the Cross, He not only died for all our sins, but also condemned sin in the flesh, in our flesh, that His Spirit may live fully and thrive in us!
But wait. . .there's more!
"For we have not an high priest which cannot be touched with the feeling of our infirmities; but was in all points tempted like as we are, yet without sin." (Hebrews 4: 15)
Jesus knows, present tense, what you are going through! He understands your struggles, and as Your representative at the right hand of God the Father (Hebrews 1: 3), you can trust that He wants to aid you in every struggle that you face, as well!
