Because Jesus has died for our sins, resurrected, and given us the ability to be forgiven through faith, we can know The LORD. Though one might think they can know God through reading about Him or meditating upon spiritual matters: true knowledge of God comes only through Jesus and faith in Him.
Intimate knowledge of God is possible only through Jesus and the forgiveness offered through His bloody sacrifice. This very thing allows us to draw close to The Father and experience Him. The LORD says in Jeremiah,
"And they shall teach no more every man his neighbour, and every man his brother, saying, Know the LORD: for they shall all know me, from the least of them unto the greatest of them, saith the LORD: for I will forgive their iniquity, and I will remember their sin no more." [Jer 31:34]
And Paul says,
"In [Jesus] we have redemption through His blood, the forgiveness of sins, according to the riches of His grace" [Eph 1:7]
Paul also says in Ephesians, “for through [Jesus] we both have access by one Spirit unto The Father.” [Eph 2:18] and he says again, “In Whom we have freedom of speech and access with confidence by the faith of Him.” [Eph 3:12] So we see that it is through Jesus “we have access by faith into this grace wherein we stand” [Rom 5:2].
It is through God’s grace, “that bringeth salvation,” that we receive forgiveness of sins by faith in “the blood of Christ, who through the eternal Spirit offered himself without spot to God.” Through this wonderful gift, as Paul says, an “unspeakable gift,” we can receive forgiveness, and thus a relationship with God wherein we can truly know Him.
You don’t have to be great or rich or popular to know God. The LORD says “from the least of them unto the greatest of them.” God wants everyone to know Him and He doesn’t place any restrictions on that knowledge. Only a lack of faith in Jesus Christ will prevent you from knowing God for it is only through Jesus Christ which knowledge of God is possible. Every other avenue to know God, to learn about Him or His character, is flawed and vain. Jesus alone offers us the experience of God.
