To be Right with God is tantamount to God being Right with Man.
I cannot be Right with God, without God' Grace - God's Word Incarnate!
For by grace you have been saved through faith, and that not of yourselves; it is the gift of God, (Ephesians 2:8 NKJV)
It's neither the written nor the spoken word that is at work today, but rather in the fullness of time, it is the Word made Flesh and dwelt among us!
And the Word became flesh and dwelt among us, and we beheld His glory, the glory as of the only begotten of the Father, full of grace and truth. (John 1:14 NKJV)
That the Kingdom of God is at hand, is the proclamation not of the ministry of Christ in words and deeds, per se, but the revelation of Christ in Glory - a new covenant - to make all things anew!
and saying, The time is fulfilled, and the kingdom of God is at hand. Repent, and believe in the gospel. (Mark 1:15 NKJV)
For God in His Righteousness made possible through Christ, Man's justification by Faith.
to demonstrate at the present time His righteousness, that He might be just and the justifier of the one who has faith in Jesus. (Romans 3:26 NKJV)
So in the fullness of time, Man is gifted the Grace to be Right with God, through Faith in Christ.
