The Lord offers a great reward to the person who will obey Him and keep his commandments.
Psalm 19:7-11 The law of the Lord is perfect, restoring the soul;
The testimony of the Lord is sure, making wise the simple.
The precepts of the Lord are right, rejoicing the heart;
The commandment of the Lord is pure, enlightening the eyes.
The fear of the Lord is clean, enduring forever;
The judgments of the Lord are true; they are righteous altogether.
They are more desirable than gold, yes, than much fine gold;
Sweeter also than honey and the drippings of the honeycomb.
Moreover, by them Your servant is warned;
In keeping them there is great reward.
Not only is there a great reward for keeping His commandments but the Lord says that your soul will be restored, you will receive wisdom, your heart will rejoice and your eyes will be enlightened. Do you need healing in your soul or wisdom and joy? Do you want insight? Then you must keep His commandments. You will have a great reward.
Matthew 5:12 Rejoice and be glad, for your reward in heaven is great; for in the same way they persecuted the prophets who were before you.
If and when you keep His commandments you will be persecuted. Again, your reward will be great and when you see the Lord you will only wish that you had obeyed more than you did. Do not fear. He will be with you.
Luke 6:35 But love your enemies, and do good, and lend, expecting nothing in return; and your reward will be great, and you will be sons of the Most High; for He Himself is kind to ungrateful and evil men.
When you love your enemies then you will have a great reward. Trust the Lord and do what He says. You will be glad.
Hebrews 10:35,36 Therefore, do not throw away your confidence, which has a great reward. For you have need of endurance, so that when you have done the will of God, you may receive what was promised.
Keep trusting Him and do not throw away your confidence in Him. When you have done the will of God for your life then you will receive what He has promised. His promises are sure. So, there are three things that if you do you will receive a great reward and these are keeping his commandments, being persecuted for your faith, loving your enemies and keeping your confidence in Christ who is faithful.
