For through Him we both have access by one Spirit to the Father.Ephesians 2:18(HCSB)
Both Jew and Gentile need to be reconciled to God. Both need God's forgiveness of their sins. Both need to be justified by faith in Christ. Both need to be redeemed and both need propitiation from their sins - i.e both need to have God's righteous wrath turned away from them due to Christ's blood sacrifice at Calvary - which brings all who believe in Jesus Christ, into full fellowship with the Father.
Both Jew and Gentile have fallen short of the glory of God and both need to be redeemed, forgiven, justified, born again - both need propitiation for their sins. And now through Jesus both Jew and Gentile have access to the Father - by means of the Holy Spirit - because of the sacrifice of Jesus Christ on the cross, for our sins.
His blood paid the price for our sins and we are declared righteous, simply by believing on His name - and it is by the power of the Holy Spirit that we are born from above and become a new creation in Christ, which gives us access into the very throne-room of our Father in heaven - hallowed be Thy wonderful name.
Thank You Father for the amazing plan of salvation whereby all sinners, both Jew and Gentile, are reconciled to You through the blood of Jesus Christ and born from above through the power of the Holy Spirit - Your plans and purposes are beyond my comprehension, but I trust in the veracity of Your word and glorify You for ever and ever, AMEN.
