For the law was given by Moses, but grace and truth came by Jesus Christ
— John 1:17

To teach and believe in God’s Grace void or separate from Truth is both dangerous and detrimental to the believer. Grace and Truth go hand in hand and are joined, much like a marriage union. This union of Grace and Truth in a believer’s heart brings, or produces, life and fruit.

Jesus Himself carried this union and displayed Grace and Truth evidenced in His life and all He did.

John 1:14And the Word was made flesh, and dwelt among us, (and we beheld his glory, the glory as of the only begotten of the Father,) full of grace and truth
— John 1:14

A.    Grace

Grace is God’s undeserved, unearned, favor. Grace cannot be bought, worked for or earned. God provided His Grace to us by giving us His only Begotten Son, His Greatest Treasure. His Grace is free, costing us nothing because Jesus paid the full price!

Being justified freely by his grace through the redemption that is in Christ Jesus
— Romans 3:24
For God so loved the world, that he gave his only begotten Son, that whosoever believeth in him should not perish, but have everlasting life
— John 3:16
For by grace are ye saved through faith; and that not of yourselves: it is the gift of God: Not of works, lest any man should boast
— Ephesians 2:8-9

We enter into God’s Grace by faith.

By whom also we have access by faith into this grace wherein we stand, and rejoice in hope of the glory of God
— Romans 5:2

God’s Grace saves us.

But we believe that through the grace of the Lord Jesus Christ we shall be saved, even as they
— Acts 15:11

We are justified by God’s Grace.

Being justified freely by his grace through the redemption that is in Christ Jesus
— Romans 3:24

Our election is by Grace.

Even so then at this present time also there is a remnant according to the election of grace
— Romans 11:5

By grace I am what I am.

But by the grace of God I am what I am: and his grace which was bestowed upon me was not in vain; but I laboured more abundantly than they all: yet not I, but the grace of God which was with me
— I Corinthians 15:10

God’s Throne is Grace.

Let us therefore come boldly unto the throne of grace, that we may obtain mercy, and find grace to help in time of need
— Hebrews 4:16

Grace makes us accepted in the beloved.

To the praise of the glory of his grace, wherein he hath made us accepted in the beloved
— Ephesians 1:6

We are called by His grace.

But when it pleased God, who separated me from my mother’s womb, and called me by his grace
— Galatians 1:15

Peter declared that God’s Grace was manifold. Manifold simply means “of various colors, various in character, abundant, increase, abounding, mighty, multitude, plenteous.”

As every man hath received the gift, even so minister the same one to another, as good stewards of the manifold grace of God
— I Peter 4:10

The Grace of God cannot be categorized by its character, method, or amount. God moves in various ways upon His creation, manifesting His Grace upon one in one manner, and upon another in another manner. 

God gives us the Measure of Grace.

But unto every one of us is given grace according to the measure of the gift of Christ
— Ephesians 4:7

God is “Abundant in Goodness” (Grace) and Truth.

And the LORD passed by before him, and proclaimed, The LORD, The LORD God, merciful and gracious, longsuffering, and abundant in goodness and truth
— Exodus 34:6

God’s Grace cannot be understood by the carnal mind of fallen man. Grace can only be experienced by and through faith.

God’s Grace is His enabling power to “be” and “do” all He has purposed for His people. Without His Grace, man cannot accomplish God’s Will no matter how great or small.

And with great power gave the apostles witness of the resurrection of the Lord Jesus: and great grace was upon them all
— Acts 4:33

Jesus Himself grew to the place of accomplishing and fulfilling all of His Father’s purpose and plan because the grace of God was upon Him.

And the child grew, and waxed strong in spirit, filled with wisdom: and the grace of God was upon him
— Luke 2:40

All we are, all we ever hope to be, all we have and will accomplish, is by and through the Grace of God.

But by the grace of God I am what I am: and his grace which was bestowed upon me was not in vain; but I laboured more abundantly than they all: yet not I, but the grace of God which was with me
— I Corinthians 15:10

No matter how difficult our circumstances may be, God’s Grace is sufficient for us. Jesus and His Grace are all we need.

And he said unto me, My grace is sufficient for thee: for my strength is made perfect in weakness...
— II Corinthians 12:9

B.    Truth

The Grace of God is not a free ticket to do as you will or to live as you please. Nor is Grace a license to sin. Quite the contrary is true.

Let not sin therefore reign in your mortal body, that ye should obey it in the lusts thereof. Neither yield ye your members as instruments of unrighteousness unto sin: but yield yourselves unto God, as those that are alive from the dead, and your members as instruments of righteousness unto God. For sin shall not have dominion over you: for ye are not under the law, but under grace. What then? shall we sin, because we are not under the law, but under grace? God forbid. Know ye not, that to whom ye yield yourselves servants to obey, his servants ye are to whom ye obey; whether of sin unto death, or of obedience unto righteousness?
— Romans 6:14-16

God’s grace leads us to Truth. Truth is a fence that protects as it restrains.

For the grace of God that bringeth salvation hath appeared to all men, Teaching us that, denying ungodliness and worldly lusts, we should live soberly, righteously, and godly, in this present world
— Titus 2:11-12

The same Grace of God that brings us Salvation also brings us restraining Truth, which teaches us to deny that which is ungodly and worldly and shows us how to live in purity before God in this present world.  Grace without union with Truth leads people into the delusion that they are free to live to themselves and in the lasciviousness of the flesh.

For there are certain men crept in unawares, who were before of old ordained to this condemnation, ungodly men, turning the grace of our God into lasciviousness, and denying the only Lord God, and our Lord Jesus Christ
— Jude 1:4

The restraining, protecting fence of truth has sanctifying power. Together, the union of Grace and Truth bring the child of God not only into the glorious experience of salvation and forgiveness of sins, but also sanctifying the believer through the Truth of God’s Word that brings man into a harmonious fellowship and relationship with God.

Sanctify them through thy truth: thy word is truth
— John 17:17
Lead me in thy truth, and teach me: for thou art the God of my salvation…
— Psalm 25:5
Let not mercy and truth forsake thee: bind them about thy neck; write them upon the table of thine heart
— Proverbs 3:3
I rejoiced greatly that I found of thy children walking in truth, as we have received a commandment from the Father
— II John 1:4
I have no greater joy than to hear that my children walk in truth
— III John 1:4

God’s unearned Favor, His Divine Grace, calls mankind, saves mankind, and gives man enabling power without cost to man. Freely given by God, Grace leads us to Truth, which protects and restrains mankind, and which leads us to walk in the paths that are pleasing God.

All the paths of the LORD are mercy (Grace) and truth…
— Psalm 25:10
