"And Abel, he also brought of the firstlings of his flock and of the fat thereof. And the Lord had respect unto Abel and to his offering:" Genesis 4:4
When we are living for and serving the Lord, we don't always see instant rewards to our obedience and act of service. This is when the accuser of the brethren comes and tries to tell us, "What's the use? There is no profit in what you are doing. Look at you, you are making all these sacrifices for God and they are to no benefit. God doesn't even notice."
Don't buy into his lies. I want to encourage you this morning that God does take notice of your faithful obedience. He sees and knows exactly what you are doing, even when it seems that He doesn't.
The blessing comes to those who are faithful and remain faithful. So continue to remain faithful in your giving of time, money and talents to the Lord. Stay faithful in what He has called you to do. Don't disregard your obedience to His word. Your obedience is your highest form of worship. And the Lord is seeking those who will worship Him, not only in spirit but in truth-- by being obedient to His word. Besides if He never blessed you for even one act of obedience, He has blessed you with more than you could have ever hoped for when He blessed you with eternal life through the sacrifice of His own Son.
So, "keep on keeping on". Remain faithful in your obedience to the Lord. Your labor is not in vain, you will be rewarded. And remember that we don't serve Him and sacrifice our lives in obedience for Him based on what He "will" do for us in return. We base it on what He has already done for us. "For God so loved the world, that he gave his only begotten Son, that whosoever believeth in him should not perish, but have everlasting life." (John 3:16)
Have a great day. God always honors those who honor Him through their obedience.
