It is written "Having made know to us the mystery of His will, according to His good pleasure which He purposed in Himself, that in the  dispensation of the fullness of times He might gather together in one all things in Christ, both which are in heaven an which are on earth in Him."  Ephesians 1:9-10.

Our salvation was fulfilled according to God's plan in the fullness of times. That is why we have been remitted from all our sins. Because of the shed blood of Jesus we have become God's children and members of His Church once and for all to enter and live in the kingdom of Heaven.

That is how we living in this present age have been saved from all our sins by believing tn the righteousness of God fulfilled by Jesus Christ.
