If the word of God is true, then we need not fear the personal expense being generous. If the word of God is true, then we need not avoid the inconvenience of helping others.
To give liberally of our time, talent, and treasure is a litmus test of our faith in God. To be eager to help others — particularly those who cannot return the favor — is a counter-intuitive investment in our future.
Be generous and helpful out of obedience. This is what God expects of his children. Be generous and helpful out of love for our heavenly Father, because doing so makes us partners with Him in His work in this world; and because doing so allows us to achieve His point of view through imitation.
We will be surprised, amazed, and humbled by the faithfulness of God when we exercise our faith in Him in these simple ways. – Luther
