Justification for all mankind
Rom 5:
18So then, just as one trespass brought condemnation for all men, so also one act of righteousness brought justification and life for all men.
Reconciliation for everything in heaven and earth including mankind and stones
Col 1:
15The Son is the image of the invisible God, the firstborn over all creation.
16For in Him all things were created, things in heaven and on earth, visible and invisible, whether thrones or dominions or rulers or authorities. All things were created through Him and for Him.
17He is before all things, and in Him all things hold together.
18And He is the head of the body, the church; He is the beginning and firstborn from among the dead, so that in all things He may have preeminence.
19For God was pleased to have all His fullness dwell in Him,
20and
through Him to reconcile to Himself all things, whether things on earth or things in heaven, by making peace through the blood of His cross.
Grace for all mankind
Titus 2:11For the grace of God has appeared, bringing salvation to all men.
Titus 3:3For at one time we too were foolish, disobedient, led astray, and enslaved to all sorts of desires and pleasures—living in malice and envy, hateful, and hating one another. 4
But when the kindness of God our Savior and His love for mankind appeared, 5He saved us, not by the righteous deeds we had done, but according to His mercy, through the washing of new birth and renewal by the Holy Spirit.
But, not all men are saved, why?
Only those that abide in Christ to the very end are considered victorious.
John 15:
9As the Father has loved Me, so have I loved you.
Remain in My love.
10If you keep My commandments, you will remain in My love, just as I have kept My Father’s commandments and remain in His love.
11I have told you these things so that My joy may be in you and your joy may be complete.
12This is My commandment, that you love one another as I have loved you.
13Greater love has no one than this, that he lay down his life for his friends.
The idea that if one thinks hard about Jesus they become the elect to whom grace applies or are reconciled with God or are justified is wrong. Christ's work on the cross justified all men, now it the duty of every man to abide in Christ's love by obeying His command to love. There's no other way to love but to work the good deeds.
