Q&A: How to explain to non-believers that the Holy Spirit's presence is a reason for faith

Mike distinguishes between 'knowing' Christianity is true and 'showing' it is true. Personal experience of God — answered prayer, life transformation, relationship with God — is valid personal evidence (it is how one can 'know'). But it is difficult to use as persuasive evidence with others because they lack your experience; they only have your testimony about it. Therefore Christians should also point to other forms of evidence when trying to convince others.
