The LONE bird perches on a branch ALONE
Christ ALONE accomplished the eternal redemption for all the elect.
The Spirit ALONE applied that eternal redemption to each individual elect personally.
All these are the free and sovereign acts of God... without man playing any part whatsoever.
When the eternal redemption has been applied to each elect, he is perfectly and completely fitted for eternal glory.
Nothing further is needed for their entrance unto their eternal glory.
God ALONE will consummate that eternal redemption for all His children at the return of Christ for His redeemed.
And ALONE means ALONE... not alone plus some effort or contribution of man.
This is the truth of salvation by God's free grace alone.
The ministry of the gospel is ordained for the well-being of God's children as they journey through this world unto their eternal glory.
The gospel ministry does not add anything to their BEING as God's children immutably destined for eternal glory.
The gospel ministry has been ordained for the spiritual well-being of God's redeemed elect; for their instruction, to make them wise concerning eternal their salvation by the free and sovereign grace of God in Jesus Christ.
Titus 2
11 For the grace of God that bringeth salvation hath appeared to all men,
12 Teaching us that, denying ungodliness and worldly lusts, we should live soberly, righteously, and godly, in this present world;
13 Looking for that blessed hope, and the glorious appearing of the great God and our Saviour Jesus Christ;
14 Who gave himself for us, that he might redeem us from all iniquity, and purify unto himself a peculiar people, zealous of good works.
15 These things speak, and exhort, and rebuke with all authority. Let no man despise thee.
