The blood of Jesus cleanses us from all unrighteousness, when we repent and accept Him as Lord and Savior.
It is the Fire of Jesus’s Spirit that actually saves you.
Dying on the cross and leaving the flesh to return home was not the great event. Jesus is my Savior as He separated from His Father’s Love to lower His Soul to our level to be born in the flesh and save us. This is why the power to test spirits is in the words given in 1John 4. They are the truth.
His great sacrifice was not dying, it was arriving. Going home to God was His Blessing. Having died and already gone to Heaven I speak from experience. Returning here to the flesh was a great sacrifice. I readily await returning home no matter the destruction of this flesh.
