God's encouragement

I don't believe in pot luck scriptures dipping into promises when it suits, because that can be dangerous, we can take things out of context. every now then you need reasurrance that you are pleasing God and putting him first, i found an amazing scripture that is just so releasing. even though i had read it before it somehow mean't more to me now and God has a way of just speaking to you allowing you to hear his voice of encouragement. the context is David is concerned that whilst he is living in a palace the ark of God remains in a tent. Nathan the prophet just gives David a simple word "whatever you have in mind go ahead and do it, for the Lord is with you". how releasing is that? for me reading that was a word in time from God, maybe today you need to hear those words too?
