The foundation and essence of the Christian life is to follow Jesus with all that we are and hold nothing back. To be a disciple means that my financial life will be inseparably connected to my worship. To be a lover of God is to be a giver; to be filled with the Spirit is to be filled with the very essence of our generous God. In other words, when we get saved our wallets must be converted as well!
And he said to him, g“You shall love the Lord your God with all your heart and with all your soul and with all your mind. This is the great and first commandment. And ha second is like it: You shall love your neighbor as yourself. Matthew 22:37-39
When we give God our lives it also includes our treasure (our time, talent and money). According to Jesus, the places and people we give our treasure to are the keepers of our heart and the objects of our affection.
For where your treasure is, there your heart will be also. Matthew 6:21
