Surely, this commandment that I am commanding you today is not too hard for you, nor is it too far away. It is not in heaven, that you should say, “Who will go up to heaven for us, and get it for us so that we may hear it and observe it?” Neither is it beyond the sea, that you should say, “Who will cross to the other side of the sea for us, and get it for us so that we may hear it and observe it?” No, the word is very near to you; it is in your mouth and in your heart for you to observe. Deuteronomy 30:11-14
Everything we need to do every good work, God in the fullness of grace, has already given us. To know God means there is no room for excuses. We simply do the very best we can with what God has given us.
