I like Matthew 6:33-34- First seek the kingdom of God and His righteousness, and everything needed shall be added to us. Here, another thing we can do is Galatians 6:1-4- We who are strong in the faith, see a brother or the family of God in a spiritual warfare, go and build them up in God's word, with prayer and the Love of Jesus. This does not mean that you have all the answers, but that you have been laboring in God's word and His will, knowing that God has the answers and truths for our lives.
When I said 'productive,' I was also talking about the body of Jesus Christ. Hebrews 10:24-25 states that fellowship is part of growing in our knowledge of God and His people. And helping the word get to others and walking in the true light of Jesus Christ. There are so many different scriptures that help with growth and connection to the living God (Jesus Christ), His people, and the world.
Philippians 4:4-8 states that we, as believers, should be thinking on these things: first, rejoicing in our Lord, be anxious for nothing, but in everything pray and be thankful, and tell our God about our requests. Know this is the blessing in doing these things: truth, honor, being just in our God, and having a pure heart. These are some things always to be mindful of.
