According to Ephesians 1: 13-14, When a person receives salvation he is sealed with the promised Holy Spirit. The presence of Holy Spirit is cardinal in Christian Life. There are many churches that attempt to explain the Holy Spirit and His presence in various ways. Some are acceptable and some are not.
What according to you is “the presence of Holy Spirit”? How can a person know that if he/she has the Holy Spirit in their everyday Christian life and what are the biblical foundations for your belief?
