1 John 4:1
Beloved, do not believe every spirit, but test the spirits to see whether they are from God, for many false prophets have gone out into the world.
Your dead shall live; their bodies shall rise. You who dwell in the dust, awake and sing for joy! For your dew is a dew of light, and the earth will give birth to the dead.
And behold, the curtain of the temple was torn in two, from top to bottom. And the earth shook, and the rocks were split. The tombs also were opened. And many bodies of the saints who had fallen asleep were raised, and coming out of the tombs after his resurrection they went into the holy city and appeared to many.
And when evening came, the boat was out on the sea, and he was alone on the land. And he saw that they were making headway painfully, for the wind was against them. And about the fourth watch of the night he came to them, walking on the sea. He meant to pass by them, but when they saw him walking on the sea they thought it was a ghost, and cried out, for they all saw him and were terrified. But immediately he spoke to them and said, “Take heart; it is I. Do not be afraid.” And he got into the boat with them, and the wind ceased. And they were utterly astounded,

He who dwells in the shelter of the Most High will abide in the shadow of the Almighty. I will say to the Lord, “My refuge and my fortress, my God, in whom I trust.” For he will deliver you from the snare of the fowler and from the deadly pestilence. He will cover you with his pinions, and under his wings you will find refuge; his faithfulness is a shield and buckler. You will not fear the terror of the night, nor the arrow that flies by day,
“For God so loved the world, that he gave his only Son, that whoever believes in him should not perish but have eternal life.
So faith comes from hearing, and hearing through the word of Christ.
