God teaches us to rejoice.

God teaches us that we should rejoice in our work. In Genesis chapter 1 we find that God created the heavens and earth. And during those 6 days God frequently looked at His work and told Himself that it was good. God showed us how He rejoiced in His work so that we too would rejoice by telling ourselves that our labor is good. God has kind intentions towards us. And as a result He teaches us about joyful paths. Another passage that strongly promotes rejoicing in our work is Ecclesiastes 2:24.

24 There is nothing better for a man than to eat and drink and tell himself that his labor is good. This also I have seen that it is from the hand of God.
