Philippians 4:9

The things which you have learned and received and heard and seen in me, practice these things (in daily life), and the God (who is the source) of peace and well-being will be with you.   

Faith and believing the promises of God take practice. Most of us didn’t attend bible school and understanding faith and how God works takes study. Training builds up spiritual muscle and takes time and willingness to trust God’s word even when we fail. God is the source of well-being and will be with us and guide us through all.
