Ephesians 2

As in his previous writings the Jewish converts, Paul again reminds them -

"For by grace are ye saved through faith; and that not of yourselves: it is the gift of God:
9 Not of works, lest any man should boast." (New Testament | Ephesians 2:8 - 9)

Again, there needed to be constant reminder to these converts that man could not be saved by the law of Moses. Over the years, the Jews continually generated more and more strict comformances to this law with the idea that they could save themselves by the law. But this is not true. We are only saved by grace. But that doesn't mean that all we have to do is declare belief and we are automatically saved. Paul continues -

"For we are his workmanship, created in Christ Jesus unto good works, which God hath before ordained that we should walk in them." (New Testament | Ephesians 2:10)

If all we had to do is declare a belief, why then hath God "ordained that we should walk in them" or in other words, keep his commandments. Why then must we be "reconciled" to God as Paul previously taught. Reconciled in my mind would suggest that we have come to the agreement of satisfying all requirements.

It is by obedience to the commandments that we become worthy to receive the Spirit or the Holy Ghost to witness and revealt to our souls the truth of all things for by doing so -

"...ye are no more strangers and foreigners, but fellowcitizens with the saints, and of the household of God;
20 And are built upon the foundation of the apostles and prophets, Jesus Christ himself being the chief corner stone;
21 In whom all the building fitly framed together groweth unto an holy temple in the Lord:
22 In whom ye also are builded together for an habitation of God through the Spirit." (New Testament | Ephesians 2:19 - 22)
