a little seed Luke 17:5-10?

Jesus friends asked him to, "Increase our faith."
Jesus said faith big as a mustard seed was all they needed (Luke 17:5). An observant Bible student noted the story behind Jesus' mustard seed promise. Jesus' friends were struggling. He asked them to forgive someone 8 times in 1 day. This was too hard (Luke 17:4). Anyone who's ever been betrayed knows the struggle to forgive. Jesus friends felt a need to grumble--this call to forgive is hard; it's truly impossible without God. Forgiveness means surrendering your anger and whatever you hold over another. Still their Lord spoke boldly--all they needed was the faith of a little seed.
A tiny seed, that's enough; that's it. A mustard seed is enough to forgive, to go to heaven, to live in this broken world. Still for 2000 years Christians want to be more faithful. Many have a felt need to do more to trust God. Scripture is clear saving faith is trusting in Christ--the living Son of God: it was the same 500, 1000, 1500, and 2000 years ago.
A great story of saving faith comes from the cross. 3 men were crucified. Jesus was in the middle. One harassed Jesus (Luke 23:39-41). But the other was saved by faith. His trust in Jesus opened the way to paradise (Luke 23:42-43). Trust in God is enough.(John 20:30-31). Like the ancient prophet said to the nation of Israel,

Look at the proud!
Their spirit is not right in them,
but the righteous live by their faith (Habakkuk 2:4 NRSV)

We strive for ways to be more righteous and honorable. We strive to be all the more deserving of God's grace and love. And all Jesus asks of us is the faith of a little seed--God will provide the rest.
