What can wash away my sin...

"If we say that we have no sin,
we are deceiving ourselves and the truth is not in us."
1 John 1:18

"Therefore, to one who knows the right thing to do and does not do it,
to him it is sin."
James 4:17

"Blessed is a man who perseveres under trial; for once he has been approved,
he will receive the crown of life which the Lord has promised to those who love Him.

Let no one say when he is tempted, “I am being tempted by God”;
for God cannot be tempted by evil, and He Himself does not tempt anyone.
But each one is tempted when he is carried away and enticed by his own lust.
Then when lust has conceived, it gives birth to sin; and when sin is accomplished, it brings forth death.

Do not be deceived, my beloved brethren.
Every good thing given and every perfect gift is from above, coming down from the Father of lights, with whom there is no variation or shifting shadow.
In the exercise of His will He brought us forth by the word of truth, so that we would be a kind of first fruits among His creatures."
James 1:12-18

The LORD is my shepherd,
I shall not want.
He makes me lie down in green pastures;
He leads me beside quiet waters.

He restores my soul;
He guides me in the paths of righteousness
For His name’s sake.

Even though I walk through the valley of the shadow of death,
I fear no evil, for You are with me;
Your rod and Your staff, they comfort me.

You prepare a table before me in the presence of my enemies;
You have anointed my head with oil;
My cup overflows.

Surely goodness and lovingkindness will follow me all the days of my life,
And I will dwell in the house of the LORD forever.

23 Psalm
