As the Word of God, He knows all things with the Father. As Jesus being born a man, he humbled himself and was born under the law and made himself nothing, taking the form of a servant, being born in the likeness of men and obedient to the law, even to the point of death on the cross. It is in this state that he dealt with the limitations of being a man which is not knowing all things. However, there are times, for the glory of God, that Christ knows people's hearts, their secrets, and the future. After his ressurrection he is exalted back to heaven, glorified back to the Father in a state of knowing all things, as he proclaims he is Alpha and Omega. There he is Lord God and Saviour on the throne with power and glory.
