The god of this Age, is actively engaged in veiling the precious truth of the Gospel of the Glory of Christ (2 Cor. 4.4); and, were it not for the spirit of wisdom and unveiling we should be effectively prevented from beholding with unveiled face the Glory of the Lord.
There is only one pathway of the knowledge of God and it is faith in Christ. It is idle to talk of knowing God unless we believe the One sent of God.
I think what is missed so often WRT prayer is that the MAIN purpose is certainly not to inform Almighty God of what is in our hearts - of course He alone looks upon and knows our hearts - but what prayer does to US. When we pray for wisdom and knowledge of God and ask it for others, we are acknowledging the critical place this has in our walk with our Lord. It ALL begins and ends with faith.
I'll post more articles of this nature.
