Now by this we know that we know Him, if we keep His commandments. He who says, “I know Him,” and does not keep His commandments, is a liar, and the truth is not in him. But whoever keeps His word, truly the love of God is perfected in him. By this, we know that we are in Him. He who says he abides in Him ought himself also to walk just as He walked. (1Jo 2:3-6 NKJ)
Simple devotion and John doesn’t hold back.
1. If we spend time in the Word, prayer and meditation (thinking on what you have read), you will know God.
2. The one that tries to bypass #1, and still claim to know God, according to John, is a liar.
3. How will it show that we are #1? It will show by our actions, walking in partnership with God.
So, read the Word, pray, meditate, then walk it out daily.
