Answer:
Reading God's word, preaching God's word, praying daily, and meeting together with other believers of God.
Explanation:
Reading God's word will make you smarter, the bible even says that if a person reads the bible that person can no longer be unsmart, it gives you wisdom. The Bible also teaches multiple different things like different types of sin, important men of God, God's wonders for his people, and what will happen in the end of days, all around very useful information. Preaching God's word will be you taking the information gained from the bible and teaching to other people so they are more willing to accept your ideas and beliefs which genuinely makes you feel good because you helped others spiritually. Praying daily is also another way to bring spiritual growth because you are talking to God perhaps you are asking for assistance, praying for someone in need, or thanking him for all the things you have received in your life. Meeting together with other believers of God is another really important way to grow spiritually. You will be connecting with like minded people who have the same beliefs as you do, and you find friendships and teachings that you can't gain elsewhere.
Hope this helps.
