Christianity is nothing without the Cross. If Jesus did not die and rise again, he is simply a man who made crazy claims about being the son of God. If the Gospel is preached devoid of the Cross, it is no Gospel at all. There is no Grace without the cross. No salvation without the cross. No heaven for us to gain. No healing for our bodies. No joy to give us strength. We are allowed into the family of God by the adoptive love of God. This is only accessible through the cross. There are to crosses though. The one that gives us access to the Father, and brings us in as engrafted adopted sons and daughters. The second is the cross that we are all required, not asked to bear.
Matthew 16:23-25
Amplified Bible (AMP)
23 But Jesus turned [a]away from Peter and said to him, Get behind Me, Satan! You are in My way [an offense and a hindrance and a snare to Me]; for you are [b]minding what partakes not of the nature and quality of God, but of men.
24 Then Jesus said to His disciples, If anyone desires to be My disciple, let him deny himself [disregard, lose sight of, and forget himself and his own interests] and take up his cross and follow Me [[c]cleave steadfastly to Me, conform wholly to My example in living and, if need be, in dying, also].
25 For whoever is bent on saving his [temporal] life [his comfort and security here] shall lose it [eternal life]; and whoever loses his life [his comfort and security here] for My sake shall find it [life everlasting].
This is the message of the Radical Cross. That a free gift if accepted requires absolute surrender.
