“This is the message which we have heard from Him and declare to you, that God is light and in Him is no darkness at all. If we say that we have fellowship with Him, and walk in darkness, we lie and do not practice the truth. But if we walk in the light as He is in the light, we have fellowship with one another, and the blood of Jesus Christ His Son cleanses us from all sin.” (1 John 1:5-7)
When God made man and gave him free choice, He was expecting that things might go wrong and had prepared a solution. Some will argue why human sacrifice; but there was no pure blood available even in the animals because the whole world fell in sin with Adam and Eve. So God have to prepare a body which has pure blood that is the Blood of His Son Jesus Christ. The blood of Jesus was the remedy planned by God before the foundation of the world says the Word of God 1 Peter 1:18-20(NKJV).
Blood of Jesus gave us New Covenant with God:
“For this is My blood of the new covenant, which is shed for many for the remission of sins.”Matthew 26:28 (NKJV)
Blood of Jesus brings us near to God:
“But now in Christ Jesus you who once were far off have been brought near by the blood of Christ.” Ephesians 2:13 (NKJV)
Blood of Jesus gives us boldness to go to Holiest place of God:
“Therefore, brethren, having boldness to enter the Holiest by the blood of Jesus, by a new and living way which He consecrated for us, through the veil, that is, His flesh,” Hebrews 10:19-20 (NKJV)
In this God did a perfect job redeeming us so that all who believe can be washed in the precious blood of Jesus so that our sinful nature completely removed and gone and we live a holy clean life. John 3:16(NKJV)Those who are believing in Jesus Christ should remember that you are sinless now; walk close to God and do not go back to your old sinful habits. If you really set apart from the sinful world, you will definitely get all the benefits of the very purpose God cleansed you for. This work everyone should constantly do to come clean in every way, not budging to the temptations the evil one puts your way. You got to be on the guard all the time, nonstop.
