All Knowing

The Bible clearly teaches that the three persons of the God-head, The Father, and the Son, and the Holy Spirit (the One True God), are All Knowing. Here are three scriptures that teach this truth. 

The Father: Known unto God are all his works from the beginning of the world. (Acts 15:18kjv)

The Son (Jesus Christ): He saith unto him the third time, Simon, son of Jonas, lovest thou me? Peter was grieved because he said unto him the third time, Lovest thou me? And he said unto him, Lord, thou knowest all things; thou knowest that I love thee. Jesus saith unto him, Feed my sheep. (John 21:17kjv)

The Holy Spirit: But God hath revealed them unto us by his Spirit: for the Spirit searcheth all things, yea, the deep things of God. For what man knoweth the things of a man, save the spirit of the man which is in him? even so the things of God knoweth no man, but the Spirit of God. (1Corinthians 2:10-11kjv)
