Dwindling religious importance and increasing secularism have taken hold of our great nation. The answer, however, is not so simple to convey in words. All relationships are based on a certain amount of give, take and love. We would never develop productive relationships without these qualities. The reason could be because you were both trying to take too much from each other.
Love is always the overriding factor.
The more love someone has for you, the more they will let you take in a relationship. God, however, has much more love for all of us and as a result allows us to take more than any human relationship would allow. Therefore, we need to give back to God in order to maintain this special relationship. When you think about this, it is such a small sacrifice just pray or talk to God. It is your response to His love for you.
