God doesn't expect us to be a walking encyclopedia of biblical knowledge. He wants us to know Him, to be in a relationship with Him. This means not only hearing but allowing our understanding of God to change the way we live. Like the wise builder who laid the foundation of his house on the rock, we learn to let our knowledge of God change us.
All I have learned in life really just boils down to this: there is only one difference between the so-called wise and the so-called foolish...and between those who are truly happy and those who are not. Those who are wise - and those who are happy - embrace and appreciate life. Those who are unhappy and unwise do not. That is all; that is the only difference.
You cannot bring about prosperity by discouraging thrift. You cannot strengthen the weak by weakening the strong. You cannot help the wage earner by pulling down the wage payer. You cannot further brotherhoold of man by encouraging class hatred. You cannot establish sound security on borrowed money. You cannot keep out of trouble by spending more than you earn. You cannot build character and courage by taking away men's initiative and independence. You cannot help men permanently by doing for them what they could and should do for themselves.
