1 Samuel 16:7 (ESV)
7 For the Lord sees not as man sees: man looks on the outward appearance, but the Lord looks on the heart.”
1 Samuel 9:1-2
1 There was a man of Benjamin whose name was Kish, the son of Abiel, son of Zeror, son of Becorath, son of Aphiah, a Benjaminite, a man of wealth. 2 And he had a son whose name was Saul, a handsome young man. There was not a man among the people of Israel more handsome than he. From his shoulders upward he was taller than any of the people.
1 Samuel 16:7 (ESV)
7 “Do not look on his appearance or on the height of his stature, because I have rejected him (speaking about David’s brother Eliab). For the Lord sees not as man sees: man looks on the outward appearance, but the Lord looks on the heart.”
2 Timothy 3:1-5 (ESV)
3 But understand this, that in the last days there will come times of difficulty. 2 For people will be lovers of self, lovers of money, proud, arrogant, abusive, disobedient to their parents, ungrateful, unholy, 3 heartless, unappeasable, slanderous, without self-control, brutal, not loving good, 4 treacherous, reckless, swollen with conceit, lovers of pleasure rather than lovers of God, 5 having the appearance of godliness, but denying its power.
Matthew 23:27-28 (ESV)
27 “Woe to you, scribes and Pharisees, hypocrites! For you are like whitewashed tombs, which outwardly appear beautiful, but within are full of dead people’s bones and all uncleanness. 28 So you also outwardly appear righteous to others, but within you are full of hypocrisy and lawlessness.
Matthew 5:8 (ESV)
8 “Blessed are the pure in heart, for they shall see God.
1 John 1:7-9 (ESV)
7 But if we walk in the light, as he is in the light, we have fellowship with one another, and the blood of Jesus his Son cleanses us from all sin. 8 If we say we have no sin, we deceive ourselves, and the truth is not in us. 9 If we confess our sins, he is faithful and just to forgive us our sins and to cleanse us from all unrighteousness.
Hebrews 4:12-13 (ESV)
12 For the word of God is living and active, sharper than any two-edged sword, piercing to the division of soul and of spirit, of joints and of marrow, and discerning ‘the thoughts and intentions of the heart. 13 And no creature is hidden from his sight, but all are naked and exposed to the eyes of him to whom we must give account.
Hebrews 9:11-14 (ESV)
11 But when Christ appeared as a high priest of the good things that have come, then through the greater and more perfect tent (not made with hands, that is, not of this creation) 12 he entered once for all into the holy places, not by means of the blood of goats and calves but by means of his own blood, thus securing an eternal redemption. 13 For if the blood of goats and bulls, and the sprinkling of defiled persons with the ashes of a heifer, sanctify for the purification of the flesh, 14 how much more will the blood of Christ, who through the eternal Spirit offered himself without blemish to God, purify our conscience from dead works to serve the living God.
Hebrews 10:19-22 (ESV)
19 Therefore, brothers, since we have confidence to enter the holy places by the blood of Jesus, 20 by the new and living way that he opened for us through the curtain, that is, through his flesh, 21 and since we have a great priest over the house of God, 22 let us draw near with a true heart in full assurance of faith, with our hearts sprinkled clean from an evil conscience and our bodies washed with pure water.
