Galatians 3:11 Where there is neither Greek nor Jew, circumcision nor uncircumcision, Barbarian, Scythian, bond nor free: but Christ is all, and in all.
The term all in was not used during the walk talks because it sounds like God is taking a gamble on us and that is not the case. But allow me to put my cards on the table.
God did not send His Son like a greeting card slogan. The Word became flesh. (John 1:14) Too often we overlook the significance of what that truly means. God gave up position, a seat on the throne, perfect oneness with God the Father and the Holy Spirit. Nothing of Him remained in the throne room. He went all in, coming in form of sinful man, getting here just as we all do, birthed. Yet without sin.
We often look at the cost of the cross because life was given and we live but rarely do we look to see what it cost Him just to get here. We do not know that in our human perspective and we will not until we get to see Him on the throne.
During the Means of Grace talk there was so much to cover about the subject that it was our longest talk. Hidden away within all that material on means of grace was this one little gem which became so precious to me. The physical man Jesus ascended to the Father but He sent the Holy Spirit to be with us. God is One. While the physical form of Jesus cannot be in us, the Holy Spirit can, and He and Jesus are One. You cannot know the Holy Spirit without knowing Jesus.
Here is the greater aspect of Christ in us and it is so important, so simple and so easily overlooked because the Holy Spirit is so tender towards us that He will not force Himself on us because we are human vessels.
Jesus Christ is not less than who He is just because He is in you.
All that Christ is, all that the Holy Spirit is, all that is One, is in you. He is all in.
