A woman from Samaria came to draw water. Jesus said to her, “Give me a drink.” (For his disciples had gone away into the city to buy food.) The Samaritan woman said to him, “How is it that you, a Jew, ask for a drink from me, a woman of Samaria?” (For Jews have no dealings with Samaritans.)

Jesus answered her, “If you knew the gift of God, and who it is that is saying to you, ‘Give me a drink,’ you would have asked him, and he would have given you living water.”

- John 4:7-10

Because of Jesus:

1) I can be 100% sure that my sins are forgiven.

“None is righteous, no, not one; no one understands; no one seeks for God. All have turned aside; together they have become worthless; no one does good, not even one.” 

“Their throat is an open grave; they use their tongues to deceive.” 

“The venom of asps is under their lips.” 

“Their mouth is full of curses and bitterness.” 

“Their feet are swift to shed blood; in their paths are ruin and misery, and the way of peace they have not known.” 

“There is no fear of God before their eyes.”

- Romans 3:10-18

He himself bore our sins in his body on the tree, that we might die to sin and live to righteousness. By his wounds you have been healed.

- 1 Peter 2:24

“as far as the east is from the west, so far does he remove our transgressions from us.”

- Psalm 103:12

Because of Jesus:

1) I can be 100% sure that my sins are forgiven.

2) I can be 100% I will live forever

The first man was from the earth, a man of dust; the second man is from heaven. As was the man of dust, so also are those who are of the dust, and as is the man of heaven, so also are those who are of heaven. Just as we have borne the image of the man of dust, we shall also bear the image of the man of heaven. 

- 1 Corinthians 15:47-49
