Wash away sin
Isa 1:16 Wash you, make you clean; put away the evil of your doings from before mine eyes; cease to do evil;
Wash your hands, cleanse your hands from evil doings. Put away of your doings and your evil heart from God's eyes; stop doing evil. The message of repentance as taught by John the Baptist and Jesus. Turn from your evil ways, not just washing hands before eating, but a change of heart and deeds.
Mat 3:7 But when he saw many of the Pharisees and Sadducees come to his baptism, he said unto them, O generation of vipers, who hath warned you to flee from the wrath to come?
Mat 3:8 Bring forth therefore fruits meet for repentance:
Mat 23:26 Thou blind Pharisee, cleanse first that which is within the cup and platter, that the outside of them may be clean also.
Mat 23:27 Woe unto you, scribes and Pharisees, hypocrites! for ye are like unto whited sepulchres, which indeed appear beautiful outward, but are within full of dead men's bones, and of all uncleanness.
Mat 23:28 Even so ye also outwardly appear righteous unto men, but within ye are full of hypocrisy and iniquity.
Isa 1:17 Learn to do well; seek judgment, relieve the oppressed, judge the fatherless, plead for the widow.
Learn to do good, learn right from wrong, and do what is required of you as God's people. Too many who claim to be born-again have not repented or learned right from wrong. Many are self willed and not following God. God hasn't changed, we must change. If we follow the world, the world is evil. The world is accepting evil behavior as normal.
Isa 1:18 Come now, and let us reason together, saith the LORD: though your sins be as scarlet, they shall be as white as snow; though they be red like crimson, they shall be as wool.
Sit down and listen, stop running around and take heed to God's word. If you repent and believe in His promises, (Receive Jesus as savior); though your sins be as scarlet, they shall be as white as snow; though they be red like crimson, they shall be as wool.
A beautiful promise of what Jesus has done for us.
1 Cor 6:9 Know ye not that the unrighteous shall not inherit the kingdom of God? Be not deceived: neither fornicators, nor idolaters, nor adulterers, nor effeminate, nor abusers of themselves with mankind,
1 Cor 6:10 Nor thieves, nor covetous, nor drunkards, nor revilers, nor extortioners, shall inherit the kingdom of God.
1 Cor 6:11 And such were some of you: but ye are washed, but ye are sanctified, but ye are justified in the name of the Lord Jesus, and by the Spirit of our God.
Isa 1:19 If ye be willing and obedient, ye shall eat the good of the land:
Isa 1:20 But if ye refuse and rebel, ye shall be devoured with the sword: for the mouth of the LORD hath spoken it.
A stern warning and reminder of God's covenant with Israel. You shall reap what you sow.
