Justified by Grace then made Heirs experientially !
Titus 3:7
7That being justified by his grace, we should be made heirs according to the hope of eternal life.
What Paul is saying, is that by Christ death, which was by the Grace of God Heb 2:9, those Christ died for were made Righteous or Justified Rom 5:19
19For as by one man's disobedience many were made sinners, so by the obedience [Death Heb 2:9] of one shall many be made righteous.
Now as a result of this, those ones He tasted death for shall be made experientially Heirs according to the Hope of Eternal life, which was promised them Titus 1:2
In hope of eternal life, which God, that cannot lie, promised before the world began;
Notice how Paul used the phrase Twice in this epistle " Hope of Eternal life" !
But because we are freely by the Grace of God Justified, made Righteous Legally, God must now through the application work of the Holy Spirit make us Heirs experientially.
Notice Paul says right after stating that we are Justified by His Grace " we should be made"according to the hope of Eternal life.
The word made is the greek word ginomai and means:
to become, i.e. to come into existence, begin to be, receive being
2) to become, i.e. to come to pass, happen
What this means, is that we should now receive New Life, to become a New Creation, a New Man as in Eph 4:24
And that ye put on the new man, which after God is created in righteousness and true holiness.
This New Man is created ktizō:
to create
a) of God creating the worlds
b) to form, shape, i.e. to completely change or transform
And so thats what God does for all who are Legally Justified by the Grace of God, He makes them Heirs experimentally by giving them New Being, New Existence, a Existence that prepares them for Eternal Life in Glory..
We are made meet Col 1:12
12Giving thanks unto the Father, which hath made us meet to be partakers of the inheritance of the saints in light:
Eternal Life is an Inheritance, and its bequeathed upon all the Heirs of Promise, the Children of Promise.
So those freely Justified by Grace, through the redemption that is in Christ Jesus Rom 3:24 which is to say His Blood Eph 1:7, they will be given a New Life corresponding to what they are, Heirs of the Kingdom , which is Eternal life.
