During Probation

"The exchange of the sinner’s vile nature to the glorious character of

the Son of God must take place during the period of probation, while Christ pleads His blood before the Father on the sinner’s account. 

If this change does not take place while Christ is our mediator, the change of the vile body will not take place at His second advent.

Now the sinner may, in obedience to the law of the Father, and by faith in the blood of the Son, attain to the moral fitness for the inheritance of the saints in light. 

Our robes of character must be made pure before Christ lays off His garments of mediation, and puts on His kingly robes. Now we may wash and be clean; but when Christ’s mediation for sinners shall cease, it will then be said, Revelation 22:10-12 ...the time is at hand.  

He that is unjust, let him be unjust still; [Justification]

and he which is filthy, let him be filthy still; [Justification]

and he that is righteous, let him be righteous still, [Sanctification]

and he that is holy, let him be holy still. [Sanctification]

And behold, I come quickly; and My reward is with Me, to give every man according as his work shall be. 

And Peter exhorts: 2 Peter 3:14 Wherefore, beloved, seeing you look for such things, be diligent, that you may be found of Him in peace, without spot, and blameless.

This washing of the soul from the stains of sin demands diligence. Paul says that: Ephesians 5:25-27 Christ also loved the church, and gave Himself for it; That He might sanctify and cleanse it with 

--the washing of water 

--by the word, 

That He might present it to Himself as glorious church, not having spot or wrinkle, or any such thing."
