Your best days are not in the past; your best days are not in the future. Your best days are inside your spirit.
What is Grace?
Grace is that place of influence/positioning, which causes a man to always have the advantage (2Cor12v9-10); it is manifestation of the beauty, glory and excellence of God in a man's life causing him to produce God-kind of results (Rom5v17).
Grace is a dispensation of God's calendar during which specific things are authorised to happen that would otherwise not (Eph3v1-2).
