'Knowledge' in the Bible

For if, after they have escaped the pollutions of the world by [personal] knowledge of our Lord and Savior Jesus Christ, they are again entangled in them and are overcome, their last condition has become worse for them than the first.

For it would have been better for them not to have [personally] known the way of righteousness, than to have known it and then to have turned back from the holy commandment [verbally] handed on to them.

but grow [spiritually mature] in the grace and knowledge of our Lord and Savior Jesus Christ. To Him be glory (honor, majesty, splendor), both now and to the day of eternity. Amen.

We [who teach God’s word] are from God [energized by the Holy Spirit], and whoever knows God [through personal experience] listens to us [and has a deeper understanding of Him]. Whoever is not of God does not listen to us. By this we know [without any doubt] the spirit of truth [motivated by God] and the spirit of error [motivated by Satan].

Beloved, let us [unselfishly] love and seek the best for one another, for love is from God; and everyone who loves [others] is born of God and knows God [through personal experience].

These things I have written to you who believe in the name of the Son of God [which represents all that Jesus Christ is and does], so that you will know [with settled and absolute knowledge] that you [already] have eternal life.

And if we know [for a fact, as indeed we do] that He hears and listens to us in whatever we ask, we [also] know [with settled and absolute knowledge] that we have [granted to us] the requests which we have asked from Him.
