24 and are
justified by his grace as a gift, through the redemption that is in Christ
Being justified, is the objective or result of obtaining the perfect life. We are all born spiritually dead thanks to Adam and his sin of cognizance. All of humanity has died because of Adam, for through him we have all sinned. That is the transmittal of the sin nature through humanity from parent to child, through all of the generations.
But now we can be treated as though we are righteous, namely not or no longer in sin. That is our perfection.
But this perfection did not come to us by means of our own work.
Freely, is the word used here in opposition to that which is earned or worked for, or that which is purchased.
Our perfection was not purchased by us, or by our effort.
But the key here are the words, gift and grace.
We were born dead. The dead cannot bring themselves back to life. Sin is a corruption or a decay. That which is decayed or corrupted, cannot make itself pure and fresh again.
So, without some supernatural help, beyond ourselves, then we have no way of having any kind of life, let alone a relationship with Him who is perfect.
So along comes God, who is perfect, has always been perfect, and will never be imperfect.
But God is also love and He has a plan for all of eternity, and for us, and through that, we receive His attention.
Our salvation, or restoration to righteousness, comes to us by means of a gift.
To acquire this, or to have it available, we need someone’s kind attention and favor. And grace is Gods favor, originating from Him, and given to us, at no cost.
We cannot deserve it, we cannot earn it, we cannot work for it. Gods favor comes to us through His grace, and by means of His effort.
Our redemption is His purchase, His payment of our debt. Sin is a transgression that carries with it, the penalty of capital execution. And that means a total and complete separation from God. And since God is everything, then we would be separated from everything.
That leaves us nothing and with nothing, if we were to remain indignant or indifferent or unbelieving.
But for the mere function of a thought, namely faith or belief in Christ, then we rid ourselves of permanent separation and gain for ourselves, eternal life.
That person who did this for us, is Jesus Christ, who is so named in this verse as well as throughout the entire Bible.
