A person doesn’t need to be smart to have the heart of God – even though it is wise to attain the heart of God.
Nowhere in God’s Word does it indicate that the sons or children of God are the ones that are smart or have a great knowledge, but His children are the ones that have the same Spirit and nature of God, which is pure love. Knowledge, wisdom, or prophecy can be a gift of God to some of His children for the work of His kingdom, but any godly gifts without the heart of God are worthless and powerless for His kingdom.
We are called to know God, but this doesn’t mean for us to have knowledge about God, but to be One in Spirit with Him. To know God or to be One in Spirit with Him is to have the same heart and Spirit as God, which is pure love, which is God’s Truth in action.
1 Cor 8:1-3 - Knowledge puffs up, but love builds up. The man who thinks he knows something does not yet know as he ought to know. But the man who loves God is known by God. NIV
Watch out for the ones that have not the love of God, but claim they have the knowledge of God.
1 Tim 1:5-7 - The goal of this command is love , which comes from a pure heart and a good conscience and a sincere faith. Some have wandered away from these and turned to meaningless talk. They want to be teachers of the law, but they do not know what they are talking about or what they so confidently affirm. NIV
God says we will know whose child a person is by their love. To love others like God has loved us is right, but the ones that loves themselves and not others are not right and still of the devil.
1 John 3:10 - This is how we know who the children of God are and who the children of the devil are: Anyone who does not do what is right is not a child of God; nor is anyone who does not love his brother. NIV
1 John 4:7-9 - Dear friends, let us love one another, for LOVE COMES FROM GOD. Everyone who loves has been born of God and knows God. Whoever does not love DOES NOT KNOW God, because God is love. NIV
When a person is living by the pure love of God, which is by God’s Holy Spirit, then they will be living the Truth of God and fulfilling the whole law of God.
1 Cor 16:14 - Do everything in love. NIV
Rom 13:10 - Therefore love is the fulfillment of the law. NIV
Through Christ and having faith in Him, which is Truth, we can be fully filled with this pure love of God. The power to overcome all evil in us and around us is the power of God’s love, which He wants to impart into us.
Eph 3:17-19 - And I pray that you, being rooted and established in love , may have power, together with all the saints, to grasp how wide and long and high and deep is the love of Christ, and to know this love that surpasses knowledge — that you may be filled to the measure of all the fullness of God. NIV
To truly have the knowledge of God or know God, a person must be filled with the love of God first, because God is pure Love, and God’s Love is pure Truth. Anyone that is living by God pure love - will be fulfilling God’s Truth as well – even though they might not be able to comprehend and explain God’s Truth with their mouths. A person continuously living by the power of God’s pure love will show the world God’s Truth (Christ), even though they might not be given the gift of prophecy to proclaim God’s Truth with words.
Heb 10:24 - And let us consider how we may spur one another on toward love and good deeds. NIV
