When we look around this fallen world, we see and hear so many incidents that seem so unjust and evil. If we let those things sink deep into our minds, we can easily fall into frustration and even have our faith come down with doubts and questions about the future. As children of God, this is where we are called to deepen our roots in His Word and grow in our faith. As the Word says in John 15:5, abiding in the relationship of Jesus is the key for us to have hope in this world as Jesus has promised that He is the Alpha and Omega, the beginning and the end: “I am the vine; you are the branches. If you remain in me and I in you, you will bear much fruit; apart from me you can do nothing.” We need to believe that our Lord is in control of everything in our life. Hence, prayer becomes an expression of hope. So, how do we use our personal and corporate prayer time as an expression of hope? In what ways could prayer effectively build believers to become His witnesses in this fallen world?
