In today’s Gospel (John 8:51-58), our Lord says:
Amen, amen, I say to you,
before Abraham came to be, I AM.
God’s covenant with Abraham is everlasting, but Christ is eternal – existing with the Father and the Holy Spirit from before time and beyond time - and only in Christ can be found the fullness of God’s revelation and grace.
Again, only in Christ can the fullness be found, not in individual Christians.
All of us are imperfect, all of us fall short: even those of us who believe explicitly in Christ.
All of us need to open ourselves more and more to the grace of Christ and receive from him the fullness of God’s grace, love, and truth.
