Exhortation-Touch

In the Old Testament, touching unclean things made one unclean.
Lev 5:2-3 2 Or if a soul touch any unclean thing, whether it be a carcase of an unclean beast, or a carcase of unclean cattle, or the carcase of unclean creeping things, and if it be hidden from him; he also shall be unclean, and guilty.

And the unclean were not allowed to touch hallowed things or holy things.
Lev 12:4 4 And she shall then continue in the blood of her purifying three and thirty days; she shall touch no hallowed thing, nor come into the sanctuary, until the days of her purifying be fulfilled.

Very interestingly, when the sin offering touched anything, it made it holy.
Lev 6:27 27 Whatsoever shall touch the flesh thereof shall be holy: and when there is sprinkled of the blood thereof upon any garment, thou shalt wash that whereon it was sprinkled in the holy place.

In the New Testament, things are a bit different. There are no things that are unclean in and of themselves. As Paul says,
Rom 14:14 14 I know, and am persuaded by the Lord Jesus, that there is nothing unclean of itself: but to him that esteemeth any thing to be unclean, to him it is unclean.

But, we are still to keep ourselves clean in Christ. There is filthiness in the world that the Christian ought not to be tangled up in and we are to be cleansed from filthiness.
2 Cor 6:17-7:1 17 Wherefore come out from among them, and be ye separate, saith the Lord, and touch not the unclean thing (aligning yourselves with unbelievers, marrying an unbeliever); and I will receive you, 18 And will be a Father unto you, and ye shall be my sons and daughters, saith the Lord Almighty. 7:1 Having therefore these promises, dearly beloved, let us cleanse ourselves from all filthiness of the flesh and spirit, perfecting holiness in the fear of God.

It is not the things, themselves, but the heart of man. Sin is not outside of us. It is in us, in the will when we disobey. We do not become clean by cleaning the outside of the cup.
Col 2:20-23 20 Wherefore if ye be dead with Christ from the rudiments of the world, why, as though living in the world, are ye subject to ordinances, 21(Touch not; taste not; handle not; 22 Which all are to perish with the using;) after the commandments and doctrines of men? 23 Which things have indeed a shew of wisdom in will worship, and humility, and neglecting of the body; not in any honour to the satisfying of the flesh.

We are in earthen vessels, our fallen bodies, struggling against sin and the disease and death of sin, but there is hope. For all those who touch Jesus are cleansed.
Matt 9:21 21 For she said within herself, If I may but touch his garment, I shall be whole. And others, Matt 14:36 36 …besought him that they might only touch the hem of his garment: and as many as touched were made perfectly whole.

Also, whomever Jesus touches is cleansed.
Mark 8:22-25 22 And he cometh to Bethsaida; and they bring a blind man unto him, and besought him to touch him. 23 And he took the blind man by the hand, and led him out of the town; and when he had spit on his eyes, and put his hands upon him, he asked him if he saw ought. 24 And he looked up, and said, I see men as trees, walking. 25 After that he put his hands again upon his eyes, and made him look up: and he was restored, and saw every man clearly.
Mark 10:13-16 13 And they brought young children to him, that he should touch them: and his disciples rebuked those that brought them. 16 And he took them up in his arms, put his hands upon them, and blessed them.

But, touching Christ, now, or being touched by Him, His blood, sanctifies us so that we can approach the most Holy without fear.
Heb 9:13-14 13 For if the blood of bulls and of goats, and the ashes of an heifer sprinkling the unclean, sanctifieth to the purifying of the flesh: 14 How much more shall the blood of Christ, who through the eternal Spirit offered himself without spot to God, purge your conscience from dead works to serve the living God?

This is wonderful promise and ought to remind us of the need to confess our sins and to be touched by Jesus so that we are cleansed and made whole.
