How do you know that the Holy Spirit dwells in you? In the early days, I wasn't sure. I did not exactly expect to see a white dove or tongues of fire landing on me, but some tangible sign would surely help. Of course, you cannot see the Holy Spirit, for he works within your heart. Now I know that when you sense Christ's presence, hear him speaking to your heart, feel the urge to call on the Father, pity anyone who is suffering, can't help wanting to witness for the Lord, experience joy at the thought of God, yearn to be one with him, or . . . – all these are signs that you have the indwelling Spirit. This is the Jesus who promised that he would be with us till the end of the age.
