Last time we finished our discussion on marriage during the Acts period. Paul's instruction though not by commandment was nonetheless through his inspired judgment and he tells the believers then that it would be "better" for the unmarried to remain in that state. This can only be rightly interpreted by understanding and acknowledging that these were necessities of the short time which was then in progress. That is, Christ's coming was close and the ministry that Paul was involved with, and encouraging others to follow him in, had an administration that held Jew to be first and an economy with its roots in the gospels and old testament Jewish scriptures. This idea is extended also to the widow:
KJG 1 Corinthians 7:39 The wife is bound by the law as long as her husband liveth; but if her husband be dead, she is at liberty to be married to whom she will; only in the Lord. (1Co 7:39 KJG)
KJG 1 Corinthians 7:40 But she is happier if she so abide, after my judgment: and I think also that I have the Spirit of God.
TBT 1 Corinthians 7:40 μακαριωτέρα δέ ἐστιν ἐὰν οὕτω μείνῃ, κατὰ τὴν ἐμὴν γνώμην· δοκῶ δὲ κἀγὼ Πνεῦμα Θεοῦ ἔχειν.
She is happier (more blessed) to remain unmarried -- and literally "and I also seem to have the Spirit of God". Do you think it is the Spirit of God to take the "short time" regimin appropriate to the ACTS and then impose it on believers today ignoring the Judgment of Acts 28?
I trust that through the reading of this great epistle that you will see the mind of God in context and discern the things that differ.
