We will not become God as Jesus is, but we will be exempted completely of sin and its curse as a Jesus-like human being. No-one can save himself by deeds. The salvation is available through faith in Jesus Christ. The good deeds according to God's will are the result of the step by step advancing sanctification and the new spirit as a gift from the Son. The atonement and belief are like the roots of a huge tree, from where the vital nourishment flows up.
Good deeds are like the fruit of the tree.
The fruits grow naturally based on the nourishment coming from the roots. So, the deeds do not cause a belief or the salvation, but the rebirth together with the work of The Holy Spirit causes the good deeds as a natural part of the new life. T he Bible is God's message to the humankind. The Bible is true in every way. It tells us about salvation history from the creation of the world until the end of this age.
