Qn 3. Why did Apostle Paul care to ask the Ephesians, “Having believed did you receive the Spirit” ? (Acts 19:2)

Unless we receive the indwelling of the Spirit, we cannot claim that we are ‘saved’ because he is the ‘deposit guaranteeing our inheritance’ ( Eph 1 : 13 )
Since it is indwelling of the Holy Spirit that imparts the righteousness by faith in Christ Jesus, how are we justified without him ? ( Gal 5 : 5 )
So it mattered to the Apostles that the people receive the Spirit after having believed. They refuted every ‘teachings of men’ that it was by ‘works’, meaning the law, that we receive this free gift of God.
So the Apostle Paul asked the Galatians, “I would like to learn just one thing from you: Did you receive the Spirit by observing the law or by believing what you heard ? Does God give you his Spirit and work miracles among you because you observe the law or because you believed what you heard ?” ( Gal 3 : 2, 5 )
Let not the Christian Sacraments of Baptism and Communion or Eucharist be the ‘works’ by which we think we receive the Spirit but only by believing the gospel. Amen.
