For there is nothing hid, which shall not be manifested; neither was any thing kept secret, but that it should come abroad.
Mark 4:22 (KJV)
Sooner or later God will always bring to light the hidden things of the heart. For us specifically this means that as our hearts are filled with the Word of God, as we allow the promises of God to take root in our hearts, sooner or later we will see the manifestation of all that God has put in us. Our role is to remain faithful, to not waver in the face of opposition, and to give thanks for the coming harvest of manifestation.
