Acts 2:1-4
When the Day of Pentecost had fully come, they were all with one accord in one place. And suddenly there came a sound from heaven, as of a rushing mighty wind, and it filled the whole house where they were sitting. Then there appeared to them divided tongues, as of fire, and one sat upon each of them. And they were all filled with the Holy Spirit and began to speak with other tongues, as the Spirit gave them utterance.
Mark 11:22
So Jesus answered and said to them, “Have faith in God.
Hebrews 10:38-39
Now the just shall live by faith;
But if anyone draws back,
My soul has no pleasure in him.”
But we are not of those who draw back to perdition, but of those who believe to the saving of the soul.
