We all need more money than is necessary to pay our bills, so that we can help someone else along life's way. If you do not have abundance, something left over, you will not be able to help others. We must understand this great truth in the light of what God teaches us in the Word about His supply and our possessions. There is a relationship there that needs to be fulfilled in order to enjoy the flow of God's prosperity. Of course, God wants you to have happiness also.
Life is meant to be enjoyed.
This too is part of the good news of Christ. You do not have to drag your body around and be miserable all your days. We do not put joy on the shelf when we become a Christian. We actually pick true joy off the shelf and really start to live and enjoy life. The reason God has set teachers in the church is so that they can motivate and encourage you to make a contribution to life and enjoy it while you are doing it.
