Jesus is Lord! Hallelujah! Praise God! The Word says it,I believe it and that settles it!
In Adam the totality of mankind were made guilty sinners subject to God's wrath.
God is not indebted to anyone,never,ever!
God was under no obligation whatsoever to save, or even make possible the salvation of anyone or everyone.
But God chose from among the mass of hell deserving sinners certain individuals to be the recipients of his grace through the death of Christ.God chose to make the salvation of his chosen ones a certainty. It is only these chosen for whom Jesus died. In due course God calls each of his elect to faith in Christ.
The whole plan of salvation is for the praise of God's glory alone: Father,Son and Holy Spirit! Amen
