If you are still in your 20s you will still develop a lot, you will get experience with new things and you will understand the world better and better on which you can apply all those things in your 30s. In your 20s you may also get married and have children, which is going to make you a different man with new responsibilities.
@Robin Bäcker I think enjoy in your 40s means that you have more freedom to enjoy life and the things that God has given you for which you have worked for. You can still work, but you probably don't need that money as much as you did in your younger days, because you have already worked hard for it.
Do you follow religious rituals such as not working on Saturdays or celebrating the holidays indicated in the old testament such as Easter, just to give an example? or do you focus only on developing your personal relationship with God?
Focus primarily on your connection with God, which is most important to Him. Faith is not about following rules and celebrating holidays. We humans will never be perfect so it is better to create a good relationship with God. Read and spread the word, and keep your heart pure. 🙏
