Romans 15:13 May the God of hope fill you with all joy and peace as you trust in him, so that you may overflow with hope by the power of the Holy Spirit.
When we get to know God, we get to realise the hope He is giving us. Before we know Him we seem to drown in the dejection of this world.
God wants us to know He has given us the Holy Spirit so we can go out and be brave in this world, not just knowing the hope we have but being able to share this hope with the people around us.
If you want to make a difference then start by showing people you have hope and explain to them how they too can have this hope. Christ has given it freely to us all!
