It is in our unwavering faith that others will see Jesus. The evidence of those who have gone before us encourages and motivates our faith and trust in God. Jesus warns us that our faith requires commitment and investment in following Him who is the pioneer and perfecter of our faith (Hebrews 12:2).

C.S. Lewis wrote "If you live for the next world, you get this one in the deal; but if you live only for this world, you lose them both." Today many think about how to get rich and how to keep it. There is not wrong with being wealthy - it is how we employ our wealth - for self for the advancement of God's kingdom.
