The Bible does not just merely suggests us to tithe and give to those who are needy, but it commands us to give to the service of God’s church. We are called to give and be generous because it is a way of glorifying God and also a way of reflecting His character in our lives. God the Father had willfully and cheerfully given His only Son to be sacrificed on the cross to redeem us. So giving is in the very fabric of the gospel, and so should it be with those who believe the gospel and live the implications of it in their lives.
It has been generally observed that Christians who tithe regularly have healthier finances. Not just tithing, but Christians involved in generous giving of themselves and sharing their resources with people who are in need often end up being better stewards of money. That is probably because their investments are often directed toward areas in life that matter the most, namely, relationships. In this passage, we learn how giving changes us, and enables us to love God’s kingdom better.
Your love for God is greatly determined by your generosity to give when people around you are in desperate need of something. Giving is not just limited to financial support (although it is essential part of your service), but it also extends to your time and spiritual support. God instituted Church to be the primary avenue in which we exercise generosity not just in terms of money, but also in terms of committing our lives (time & talents) for the growth of the church. Church is a community which reveals our love for God and our understanding of His generosity in the way we conduct ourselves with people.
