We know we know the Lord because:
6. We have overcome the world and Satan
“I write to you, little children, Because your sins are forgiven you for His name’s sake. I write to you, fathers, Because you have known Him who is from the beginning. I write to you, young men, Because you have overcome the wicked one.I write to you, little children, Because you have known the Father. I have written to you, fathers, Because you have known Him who is from the beginning. I have written to you, young men, Because you are strong, and the word of God abides in you, And you have overcome the wicked one.” 1 John 2:12-14 NKJV
“For whatever is born of God overcomes the world. And this is the victory that has overcome the world – our faith.” 1 John 5:4 NKJV
“We know that whoever is born of God does not sin; but he who has been born of God keeps himself, and the wicked one does not touch him.” 1 John 5:18 NKJV
Because we know the Father; because we are born of God; because His word abides in us; because our faith is in Him; because we keep ourselves and choose to not sin – therefore we have overcome the wicked one and he cannot touch us.
7. We hate the world and the things of the world
“Do not love or cherish the world or the things that are in the world. If anyone loves the world, love for the Father is not in him. For all that is in the world — the lust of the flesh [craving for sensual gratification] and the lust of the eyes [greedy longings of the mind] and the pride of life [assurance in one’s own resources or in the stability of earthly things] — these do not come from the Father but are from the world [itself]. And the world passes away and disappears, and with it the forbidden cravings (the passionate desires, the lust) of it; but he who does the will of God and carries out His purposes in his life abides (remains) forever.” 1 John 2:15-17 AMP
The child of God, who knows God, does not love the world or things of the world. The more we come to know the Father; the more time we spend with Him; the less we desire worldly carnal things.
8. We are one with the Body of Christ
“They went out from our number, but they did not [really] belong to us; for if they had been of us, they would have remained with us. But [they withdrew] that it might be plain that they all are not of us.” 1 John 2:19 AMP
Those who know the Father have fellowship with Him and with each other. They are not exclusive, neither do they separate themselves. They do not fight against each other, but they do everything to walk in peace with each other.
9. We are anointed by the Spirit
“But you have an anointing from the Holy One, and you know all things. I have not written to you because you do not know the truth, but because you know it, and that no lie is of the truth. Who is a liar but he who denies that Jesus is the Christ? He is antichrist who denies the Father and the Son. Whoever denies the Son does not have the Father either; he who acknowledges the Son has the Father also. Therefore let that abide in you which you heard from the beginning. If what you heard from the beginning abides in you, you also will abide in the Son and in the Father. And this is the promise that He has promised us — eternal life. These things I have written to you concerning those who try to deceive you. But the anointing which you have received from Him abides in you, and you do not need that anyone teach you; but as the same anointing teaches you concerning all things, and is true, and is not a lie, and just as it has taught you, you will abide in Him.” 1 John 2:20-27 NKJV
You cannot fake the anointing – you are either anointed or you are not. Those who know the Father also know and recognize the anointing of the Holy Spirit.
10. We know the truth that sets us free
“I have not written to you because you do not know the truth, but because you know it, and that no lie is of the truth.” 1 John 2:21 NKJV
“And you shall know the truth, and the truth shall make you free.” They answered Him, ‘We are Abraham’s descendants, and have never been in bondage to anyone. How can You say, ‘You will be made free’?’ Jesus answered them, ‘Most assuredly, I say to you, whoever commits sin is a slave of sin. And a slave does not abide in the house forever, but a son abides forever. Therefore if the Son makes you free, you shall be free indeed.’ ” John 8:32-36 NKJV
We know the Truth because we know the Father. The Truth sets us free from sin and from the bondage of sin. We are free indeed.
11. Because we acknowledge God and His Son Jesus Christ
“Who is a liar but he who denies that Jesus is the Christ? He is antichrist who denies the Father and the Son. Whoever denies the Son does not have the Father either; he who acknowledges the Son has the Father also. Therefore let that abide in you which you heard from the beginning. If what you heard from the
beginning abides in you, you also will abide in the Son and in the Father. And this is the promise that He has promised us —
eternal life.” 1 John 2:22-25 NKJV
We know the Father, and we know Jesus, because we acknowledge that He is Lord, God and Savior. Because we believe, we have eternal life now.
