Many times in life we tend to lower our expectations. This is sometimes considered wisdom especially in relation to dealing with people. However we need to be careful this doesn't become the norm in our life. Yes people will disappoint us, yes Gods timing many times is not ours, but as believers were called to be like Jesus. What was He like?
He lived a lifestyle of expectation, a life of true living faith. He had the ability to believe His Father and also to believe in people. He wouldn't have died for humanity if He didn't.
In one account He told a woman to "go and sin no more" this wasn't just a catchy Jesus saying, it was living faith. When He said "he who believes in me, the works that I do he will do also".
Again He's always challenging, always raising expectation, always believing. This is how we're called to live. Always believing God, always raising our expectation, always trusting the God that is able to do exceedingly abundantly above all that we ask or think, according to the power that works in us.
Always preaching Jesus is the way, always bringing the reality of the Kingdom of God in our midst!
