Grace - God's favor; peace - the effects of that favor in the communication of spiritual and temporal blessings.
Through the knowledge of God - Εν επιγνωσει· By the acknowledging of God, and of Jesus our Lord. For those who acknowledge him in all their ways, he will direct their steps. Those who know Christ; and do not acknowledge him before men, can get no multiplication of grace and peace.
Grace and peace be multiplied unto you through the knowledge of God, and of Jesus our Lord - That is, grace and peace abound to us, or may be expected to be conferred on us abundantly, if we have a true knowledge of God and of the Saviour. Such a knowledge constitutes true religion: for in that we find “grace” - the grace that pardons and sanctifies; and “peace” - peace of conscience, reconciliation with God, and calmness in the trials of life. See the notes at John 17:3.
Sanctification is a progressive work. The successive steps are set before us in the words of Peter: “Giving all diligence, add to your faith virtue; and to virtue knowledge; and to knowledge temperance; and to temperance patience; and to patience godliness; and to godliness brotherly kindness; and to brotherly kindness charity. For 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.” “Wherefore the rather, brethren, give diligence to make your calling and election sure; for if ye do these things, ye shall never fall; for so an entrance shall be ministered unto you abundantly into the everlasting kingdom of our Lord and Saviour Jesus Christ.” MYP 116.1
Here is a course by which we may be assured that we shall never fall. Those who are thus working upon the plan of addition in obtaining the Christian graces, have the assurance that God will work upon the plan of multiplication in granting them the gifts of His Spirit. MYP 116.2Read in context »
The actual progress of the soul in virtue and divine knowledge is by the plan of addition—adding constantly the graces which Christ made an infinite sacrifice to bring within the reach of all. We are finite, but we are to have a sense of the infinite. 1MCP 94.3Read in context »
The only safety for the Christian is to be unwearied in his efforts to live on the plan of addition. The apostle shows the advantages to be gained in thus doing. For those who add grace to grace, God will work on the plan of multiplication, so that the graces will be in and abound in the religious life and he will not “be barren nor unfruitful....” Those abounding in the Christian graces will be zealous, lively, vigorous in all practical Christianity, and will practice righteousness—just as the branch abiding in the vine will produce the same fruit that the vine bears....
