What blood speaks better than the blood of Jesus?
It is the sprinkling blood that speaks better than the blood of Abel and Jesus.
The history of mankind had continued long before Jesus' First Coming. But when Jesus came to this earth, all that timeline was nullified, and history began again with Day 1 of Year 1.
Now, the time has come for the kingdom of God to be established in reality, which is the sinless world to come. The sprinkled blood which speaks better than the blood of Abel the first martyr and Jesus the mediator of the new covenant is covering the whole world now. That is the eternal gospel, the Word of the new covenant, which is being declared by the Spirit of Truth who has come to this earth in flesh.
Just saying" by the blood of Jesus" is not the sprinkling of the blood at all. When Jesus died on the cross, he did not carry all of our sins from the past, present and the future; what he did was obeying the Word of God.
Seek the Truth, and receive the eternal gospel proclaimed through the Spirit of Truth, and return to the only Father God.
