We wander like lost sheep, true; but God is a faithful shepherd who pursues us relentlessly. We have our ups and downs, zealously believing one day and gloomily doubting the next, but He is faithful. We break our promises, but He doesn't break His. Discipleship is not a contract in which if we break our part of the agreement He is free to break His; it is a covenant in which He established the conditions and guarantees the results...
All the persons of faith I know are sinners, doubters, uneven performers. We are secure not because we are sure of ourselves but because we trust that God is sure of us.
I conclude with a quote from Mother Teresa..
God's Trust - I know God will not give me anything I can't handle. I just wish that He didn't trust me so much. Mother Teresa
