I contend that most Christians withhold more of their wealth for personal comforts than the Bible instructs.
Proverbs 3:9-10: "Honor the Lord with your wealth then your barns will be filled with plenty, and your vats will be bursting with wine".
Mark 12:41-44: "Jesus sat down opposite the place where the offerings were put and watched the crowd putting their money into the temple treasury. Many rich people threw in large amounts. But a poor widow came and put in two very small copper coins, worth only a few cents. Calling his disciples to him, Jesus said, 'Truly I tell you, this poor widow has put more into the treasury than all the others. They all gave out of their wealth; but she, out of her poverty, put in everything—all she had to live on'.
So, Jesus (and Proverbs) surely are saying that REALLY bountiful giving is wise and in keeping with God's wishes. I was thinking of this when visiting a pretty passionate pastor and noticed that his house was super large, super nice, and that he had all kinds of valuable collections and expensive hobbies. If Christians really believe that there is an afterlife of eternal paradise after a brief time in this world, why withhold so much for personal pleasure? The appearance is that many are "hedging their bets" in case they are mistaken about the afterlife so that they can be very comfortable here on earth and not have any regrets. And so, I am contending for debate that most Christians don't give in a way that matches what is taught in the Bible.
