Cleansing Vessel

Isaiah 66:20 (King James )
And they shall bring all your brethren for an offering unto the LORD out of all nations upon horses, and in chariots, and in litters, and upon mules, and upon swift beasts, to my holy mountain Jerusalem, saith the LORD, as the children of Israel bring an offering in a clean vessel into the house of the LORD.

Context: God detests human efforts to please him by keeping ritual laws without respecting moral laws. Sacrifices meant nothing to God if they were offered by merciless, unjust people or immorality. Rituals and outward righteousness but inward hypocrisy is not what God desires. These detestable things that are associated with idol worship, superstition and immorality will not help purify them but bring judgement. Only when they offer themselves as a pleasing sacrifice with repentance, made clean inside out by the Lord, that is acceptable. Shows importance of being made right before God by asking forgiveness. How can a rusty knife be used in surgery if it is not clean and sharpened first. How can we be used by God if we are not first washed by him. Mark 13:1-17

1 John 1:9 (New International Version)
9If we confess our sins, he is faithful and just and will forgive us our sins and purify us from all unrighteousness.

Context: John wrote to encourage and strengthen believers that only the blood of Jesus, his Son, purifies us from all sin. Some claimed that they live a sinless life of perfection, others say they never sin but we all know we live in a fallen world and no one is perfect except God. Additionally, although perfection and idealistic is not attainable at least here, but forgiveness and cleansing of Jesus blood gives us the free gift to heaven where it is without sin and this available to everyone who believes.

2 Timothy 2:21 (New American Standard Bible)
Therefore, if anyone cleanses himself from these things, he will be a vessel for honor, sanctified, useful to the Master, prepared for every good work.

Context: Paul encourages believers to present themselves to God as one approved, a workman who does not need to be ashamed and who correctly handles the word of truth. And to be someone that God can use for noble purposes, he needs to be cleaned and made holy before God to use as instrument to do his good works.

Leviticus 14:2-9 (NIV)
² "These are the regulations for the diseased person at the time of his ceremonial cleansing, when he is brought to the priest: ³ The priest is to go outside the camp and examine him. If the person has been healed of his infectious skin disease, ⁴ the priest shall order that two live clean birds and some cedar wood, scarlet yarn and hyssop be brought for the one to be cleansed. ⁵ Then the priest shall order that one of the birds be killed over fresh water in a clay pot. ⁶ He is then to take the live bird and dip it, together with the cedar wood, the scarlet yarn and the hyssop, into the blood of the bird that was killed over the fresh water. ⁷ Seven times he shall sprinkle the one to be cleansed of the infectious disease and pronounce him clean. Then he is to release the live bird in the open fields. ⁸ "The person to be cleansed must wash his clothes, shave off all his hair and bathe with water; then he will be ceremonially clean. After this he may come into the camp, but he must stay outside his tent for seven days. ⁹ On the seventh day he must shave off all his hair; he must shave his head, his beard, his eyebrows and the rest of his hair. He must wash his clothes and bathe himself with water, and he will be clean.

Context: Ceremonial ritual for cleansing, and the two birds represented the person being cleaned and the other killed showed the death the person might have suffered but it was atoned for his uncleanness.. This freed bird symbolized the person's physical and spiritual restoration. However we know that when Jesus came, he was the ultimate sacrifice and his blood is the strongest cleaning agent to remove the hard grind sins that people have in their life. It is only through asking forgiveness, trusting and turning to him that he begins purifying our hearts.
