God desires our very best. Are we giving Him our best or does He get leftovers? Leftover time, if there is any. Leftover giving if there is anything left to give (resources, energy, talents, gifts, etc.).
God deserves: Our very best - our best time.
You and the Lord have to decide what time that is for you. Early morning is best because you have the whole day in front of you and you have almost NO distractions. But, everyone has to do what works for them. Plan it. If you don't, at best, He will only get leftovers.
God deserves: Our best resources, energy, talents, gifts, etc.
How can we give Him what He desires and deserves? Put Him first. Give Him the best part of our day. Give Him the best of our resources, talents, gifts, energy, etc.
2 Timothy 2:15: "Do your best to present yourselves to God as one approved, a workman that does not need to be ashamed and who correctly handles the Word of Truth."
I am reminded of the old hymn, Give of Your Best to the Master. He deserves nothing less than our best.
