Psalm 119:33

Teach me, O Lord the way of Your statutes, and I will (steadfastly) observe it to the end. Give me understanding (a teachable heart and ability to learn), that I may keep your law; and observe it with all my heart. 

With God, there will always be more to learn. We will never come to a complete understanding of all that God can do. When we keep an open heart to God and remain teachable, we will leave an open the door to learning. A willing heart is all that it requires and our time.
