The article presents issues connected with God's salvific economy which realises itself from the beginning of the world up to now. Christian history shows that the Church is included in the Revelation and God's salvific plans. God's entire economy is the creation of Three Divine Persons and its aim is to lead creatures to gain a perfect unity and love of The Trinity. God' economy organises the reality as the Revelation's and Salvation's history. It encloses the entire reality which gradually reveals itself while being realised in the world's history. So, the notion of THE God's history of salvation and Revelation refers to God's activity in cooperation with humans. The eschatological times were revealed in the Resurrection of Christ and were made authenticated in Him. The God's economy, disclosed gradually in the history, has begun in conjunction with the world's and human's creation. The Old Testament's economy was orientated to the Event of Jesus Christ, who made it executed. At last, it was Him (His Revelation and Salvation), who authenticated it and opened IT to infinity. And the New Testament's economy speaks directly about the God's economy. It is marked Jesus Christ teaches directly that His entering the world aimed at a fulfilment of the Father's salvific will. Finally, the author of the article raises the problem of difficulties in reconciling God's salvation plan with human's freedom. He marks it is possible only in God and His wisdom, as it is only He who knows humans and their possibilities completely.
