Every believer has worldly responsibilities. Even so, we must never allow those to supplant our walk with God. God does not want us to be divided or distracted. Jesus commands us not to worry about earthly things, such as food and clothing (Matthew 6:25–34) because He will provide for us. This doesn’t mean that we can shirk our responsibilities, sit back, and expect God to handle the duties that He has given us the means to manage. Christians must work to provide for ourselves and our families (2 Thessalonians 3:10). Yet, we’re not to become so worried and preoccupied with the practical cares of this world that we neglect our spiritual life (Colossians 3:2). Our priority is always God and His kingdom (Matthew 6:33). Believers are encouraged to trust God's promise that if we seek His will, God will provide for our material needs (not to be confused with our wants).
Everyone has been anxious at some point in their lives. Some struggle more with this issue than others. The Bible instructs Christians to manage our daily obligations, but not worry about them so much that they distract us from God’s kingdom. For instance, a Christian works to provide for himself but shouldn’t become unduly worried about how the economy will affect his retirement fund. He can only fulfill his responsibilities; the future is in God's hands. Even Christian ministers might worry about the "success" of the ministry, i.e., number of conversions. But Christ only commands us to spread the good news of the gospel to the ends of the earth; the Holy Spirit is responsible for the conversions (John 3:5–8). Spiritually, believers in Christ have no need to fret: our salvation is secure in Christ, and we are free from both condemning guilt and the fear of death (Romans 8:1, 35–39; Hebrews 2:14–15). As Christians, we are called to follow Christ’s commands, but we are not called to be anxious about the results.
