There are laws that govern the physical universe. Gravity is one such law. It involves all matter. There is a constant; there are observable relationships.
There are laws that govern the spiritual universe. Reaping\sowing is an example of this kind of law. Focusing the heart (as in prayer, meditation and chanting) to connect the spiritual and the physical is another.
There are laws that govern God’s Kingdom. One of the first laws is that faith accesses God’s promises. Faith is the pair of hands held out to receive what God gives. Faith is confidence that God has the power, resources and desire to fulfill his promises.
Another law of the Kingdom is that the best attitude of heart focus is love. It is heart-focus that reaches into the spiritual realm. Prayer is a way to focus our hearts. We can prayer with hate or anger in our hearts. If we do, we can still succeed in connecting with the spiritual realm. Love has a motivation that invokes results that agree with God’s purposes more. That’s one reason why worship is an important factor in following Jesus. Worship should be an expression of love.
