Acts 10:43 (KJV) To him give all the prophets witness, that through his name whosoever believeth in him shall receive remission of sins.
Jesus Christ the Messiah, the son of GOD, Emanuel (GOD with us) has been foretold by the prophets through out the Old Testament. It has been declared that whosoever believes in Jesus Christ will be forgiven of their sins and receive eternal life with GOD. One such prophesy is in Isaiah 42:1-9 (KJV) “Behold my servant, whom I uphold; mine elect, in whom my soul delighteth; I have put my spirit upon him: he shall bring forth judgment to the Gentiles. [2] He shall not cry, nor lift up, nor cause his voice to be heard in the street. [3] A bruised reed shall he not break, and the smoking flax shall he not quench: he shall bring forth judgment unto truth. [4] He shall not fail nor be discouraged, till he have set judgment in the earth: and the isles shall wait for his law. [5] Thus saith God the LORD, he that created the heavens, and stretched them out; he that spread forth the earth, and that which cometh out of it; he that giveth breath unto the people upon it, and spirit to them that walk therein: [6] I the LORD have called thee in righteousness, and will hold thine hand, and will keep thee, and give thee for a covenant of the people, for a light of the Gentiles; [7] To open the blind eyes, to bring out the prisoners from the prison, and them that sit in darkness out of the prison house. [8] I am the LORD: that is my name: and my glory will I not give to another, neither my praise to graven images. [9] Behold, the former things are come to pass, and new things do I declare: before they spring forth I tell you of them.”
There are many promises that come through faith in Jesus Christ with some listed in Isaiah above.
The LORD said in Isaiah 1:16-20 (KJV) “Wash you, make you clean; put away the evil of your doings from before mine eyes; cease to do evil; [17] Learn to do well; seek judgment, relieve the oppressed, judge the fatherless, plead for the widow. [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. [19] If ye be willing and obedient, ye shall eat the good of the land: [20] But if ye refuse and rebel, ye shall be devoured with the sword: for the mouth of the LORD hath spoken it.”
He promises forgiveness of sin if we repent, turning to Him.
We have this forgiveness through the shed blood of Jesus Christ on the cross. This is not because of who we are, or what we have done but because of His amazing grace. It is GOD’s pleasure to do this. “Ephesians 1:3-7 (KJV) Blessed be the God and Father of our Lord Jesus Christ, who hath blessed us with all spiritual blessings in heavenly places in Christ: [4] According as he hath chosen us in him before the foundation of the world, that we should be holy and without blame before him in love: [5] Having predestinated us unto the adoption of children by Jesus Christ to himself, according to the good pleasure of his will, [6] To the praise of the glory of his grace, wherein he hath made us accepted in the beloved. [7] In whom we have redemption through his blood, the forgiveness of sins, according to the riches of his grace;”
There is no one here on earth now that does not need forgiveness and we are only justified through Jesus Christ, for it is written “Romans 3:22-24 (KJV) Even the righteousness of God which is by faith of Jesus Christ unto all and upon all them that believe: for there is no difference: [23] For all have sinned, and come short of the glory of God; [24] Being justified freely by his grace through the redemption that is in Christ Jesus:”

Therefore be encouraged today to call on the name of Jesus Christ, to turn to Him and ask Him to forgive your sins. As we receive His forgiveness let us also forgive those who hurt us following the example of Jesus Christ “Luke 23:34 (KJV) Then said Jesus, Father, forgive them; for they know not what they do. And they parted his raiment, and cast lots.” Knowing that “Matthew 6:14-15 (KJV) For if ye forgive men their trespasses, your heavenly Father will also forgive you: [15] But if ye forgive not men their trespasses, neither will your Father forgive your trespasses.”
