How do you make your calling sure? By faith alone? Or by faith and works?

What does it mean to make one's calling and election sure? Aren't those who are called and elected already saved?

And how do you make your calling and election sure, by faith alone? or by faith and works?

If they are already saved, why does Scripture say?
2 Peter 1:4-10

King James Version (KJV)
⁴Whereby are given unto us exceeding great and precious promises: that by these ye might be partakers of the divine nature, having escaped the corruption that is in the world through lust.
⁵And beside this, giving all diligence, add to your faith virtue; and to virtue knowledge;
⁶And to knowledge temperance; and to temperance patience; and to patience godliness;
⁷And to godliness brotherly kindness; and to brotherly kindness charity.
⁸For if these things be in you, and abound, they make you that ye shall neither be barren nor unfruitful in the knowledge of our Lord Jesus Christ.
⁹But he that lacketh these things is blind, and cannot see afar off, and hath forgotten that he was purged from his old sins.
¹⁰Wherefore the rather, brethren, give diligence to make your calling and election sure: for if ye do these things, ye shall never fall:

What role do works play in our salvation?

Matthew 25:41-46

King James Version (KJV)

 ⁴¹Then shall he say also unto them on the left hand, Depart from me, ye cursed, into everlasting fire, prepared for the devil and his angels:
 ⁴²For I was an hungred, and ye gave me no meat: I was thirsty, and ye gave me no drink:
 ⁴³I was a stranger, and ye took me not in: naked, and ye clothed me not: sick, and in prison, and ye visited me not.
 ⁴⁴Then shall they also answer him, saying, Lord, when saw we thee an hungred, or athirst, or a stranger, or naked, or sick, or in prison, and did not minister unto thee?
 ⁴⁵Then shall he answer them, saying, Verily I say unto you, Inasmuch as ye did it not to one of the least of these, ye did it not to me.
 ⁴⁶And these shall go away into everlasting punishment: but the righteous into life eternal.

Note that the goats did nothing.  They did nothing at all.  They did not commit any evil sin.  They did not jump on or beat up the innocent.  They did not steal their food.

They simply did nothing at all.

Note also that they called Jesus, Lord.

Faith without works is dead, being alone.  (James 2:17)

Sincerely,

De Maria
