We cannot do anything worthwhile in this Kingdom without money. Money is the vehicle on which the Gospel runs. The Bible says, "...My cities through prosperity shall yet be spread abroad..." (Zechariah 1:17). Serving God will cost you something. In the Early church, those who had lands and houses sold them and brought the money for the work of the Gospel. The Scripture says, "Neither was there any among them that lacked... and brought the prices of the things that were sold, and laid them down at the apostles' feet..." (Acts 4:34–35). They gave selflessly so the Gospel could spread. Serving God is not merely attending church; it requires contribution.
You serve God with giving. Giving is an act of obedience, a tangible way to participate in the expansion of God's kingdom. Coming to church is not service. Service means you are doing the work. Everybody may not carry a camera or be an usher, but everybody must be heavily involved in giving—alongside prayer and soul winning. Heavy involvement is required because the time is short.
God expects us to contribute to the Gospel financially, just as He expects us to pray and win souls. The Scripture also says, "...For unto whomsoever much is given, of him shall be much required..." (Luke 12:48). And we are reminded, "...He which soweth sparingly shall reap also sparingly; and he which soweth bountifully shall reap also bountifully... God loveth a cheerful giver" (2 Corinthians 9:6–7).
Do not separate giving from serving. If you love the Gospel, invest in it. If you believe in the work, support it. Make giving part of your obedience to God. When you give for the sake of the Gospel, you are laying up treasure both now and in the world to come.
