By addressing the WHY question more than the WHERE or WHO or HOW and HOW MUCH to give, it is easier to refocus and re-align my heart/mind/spirit according to God's will. As stated below, when I answer the why, it becomes clear to a believer like me to act upon not just think about the essence of giving back to the One who gives. My prayer is that God will transform my attitudes, thoughts, emotions and motives that need to change so that I may worship Him in love.
God may be pleased, indeed delighted, with us even if we are giving the wrong amount, even if we are giving to unworthy or inappropriate cause. As we learn more about stewardship, of course, we will want to grown in those respects. We can spend a lifetime trying to find better ways of fulfilling God's expectations. But, for starters, our principal concern in giving should not be where to give, or how to give, or how much to give. First, let us focus on the why. If we give with hearts full of devotion for the God who loves us, then the questions of where and how and how much will work themselves out in time.
...worship is essential to faith... sacrifice is essential to worship. Why is that? Because worship, almost by definition, is the opposite of self-centeredness. Doing this always involves some element of self-denial or sacrifice, giving up something that we value, giving up attention to our wants and our needs in order to focus on God…
When we give cheerfully as an act of worship, the very act of giving moves us to lose interest in ourselves and to devote ourselves to God.
