What you believe about the future shapes how you live today. If the future is only bleak, one may hoard, seeking as much comfort today as possible. If the future is hopeful, even our current challenges become manageable.
In Matthew, Jesus makes it clear that suffering for His sake is inevitable in the Christian life. If you are a ChirstIan, you must deny yourself and let go of everything contray to the Kingdom. But Jesus doesn't leave us with challenges alone. He shows us our future hope - and it changes the way we live today.
