“God knows my heart.” is a common phrase that both Christians and non-Christians use. And sadly, it’s carelessly thrown about to excuse or approve of the faithless, opinionated, and self-righteous way many of us choose to live.
Rarely is this phrase used by a truly penitent and humble heart that worships the LORD Almighty in the splendor of holiness—in spirit and in truth (1 Chron 16:29 and Jn 4:23-24).
So how can we know for certain if our hearts are the penitent or proud ones when we say, “God knows my heart.”?
We know by how God Almighty says we can know. We test our hearts by what comes out of our mouths (Mt 12:34-37, Lk 6:43-46), with God’s perfect and infallible Word of truth.
This God—His way is perfect;
the word of the LORD proves true;
He is a shield for all those who take refuge in Him.
~2 Samuel 22:31
All Scripture is breathed out by God and profitable for teaching, for reproof, for correction, and for training in righteousness, that the man of God may be complete, equipped for every good work.
~2 Timothy 3:16-17
We are commanded by God to “test everything” (1 Th 5:21). The Greek word used for “test” in this verse as well as in Romans 12:2, 1 Corinthians 3:13, 2 Corinthians 13:5, and 1 John 4:1 is δοκιμάζω, transliterated: dokimazō which means: to test, examine, prove, scrutinize (to see whether a thing be genuine or not), as metals.
Who is wise and understanding among you? By his good conduct let him show his works in the meekness of wisdom. But if you have bitter jealousy and selfish ambition in your hearts, do not boast and be false to the truth. This is not the wisdom that comes down from above, but is earthly, unspiritual, demonic. For where jealousy and selfish ambition exist, there will be disorder and every vile practice. But the wisdom from above is first pure, then peaceable, gentle, open to reason, full of mercy and good fruits, sincere and impartial. And a harvest of righteousness is sown in peace by those who make peace.
~James 3:13-18 (emphasis, mine)
The Arrogant Heart Sounds Like This
God knows my heart. I don’t have to prove anything to anyone. My relationship with God is personal and I have the right to live it the way I believe God wants me to. And I don’t need to read or study the Bible to know if God is please with me. I know He knows my heart and He knows I do all things to please Him by being a good parent, child, sibling, friend, worker, neighbor, citizen, etc.
A fool takes no pleasure in understanding,
but only in expressing his opinion.
~Proverbs 18:2
The Humble Heart Sounds Like This
God knows my heart. And I pray daily that He searches, knows, and tests it (Ps 139:23-24) because I trust He will strengthen, comfort, refresh, exhort, and rebuke me as I need for all circumstances—that the essence of my life will honor, glorify, and magnify the name of Jesus with every breath He provides (Heb 12:6, 10-11; Titus 2:11-14).
Every way of man is right in his own eyes,
but the LORD weighs the heart.
~Proverbs 21:2
Which is yours: a penitent heart or a proud heart?
If the former, then give thanks and praise and all glory to God Most High for the riches of His grace lavished upon you through Christ Jesus (Eph 2:4-10)!
If the latter, then repent and give thanks and praise and all glory to God for His enduring patience and mercy lavished upon you through Christ Jesus (Rm 2:4-8)!
Sing to the LORD, all the earth!
Tell of His salvation from day to day.
Declare His glory among the nations,
His marvelous works among all the peoples!
For great is the LORD, and greatly to be praised,
and He is to be feared above all gods.
For all the gods of the peoples are worthless idols,
but the LORD made the heavens.
Splendor and majesty are before Him;
strength and joy are in His place.
Ascribe to the LORD, O families of the peoples,
ascribe to the LORD glory and strength!
Ascribe to the LORD the glory due His name;
bring an offering and come before Him!
Worship the LORD in the splendor of holiness;
tremble before Him, all the earth;
yes, the world is established; it shall never be moved.
Let the heavens be glad, and let the earth rejoice,
and let them say among the nations, “The LORD reigns!”
~1 Chronicles 16:23-31
