Grace of God is unmerited favor, something we did not deserve. God gives grace to us through His Son Jesus Christ and His Holy Spirit.
Are there anything left for Christians to do ? After a Christian receives Jesus Christ and the Holy Spirit, he or she lives and walks in the Spirit. The Christian at this point realizes that he or she now depends on the Holy Spirit and not on his or her own power.It took me a very long time to realize this.
Does that mean that a Christian life is an easy street ? Let us look at the life of apostle Paul. After he became a Christian through the grace of God, he still suffered many things, he was stoned, beaten, experienced ship wrecks,sleepless nights, hunger etc. In today's world like in the West it seems we hardly experience those.
Shall we ask God, is there anything He can use us for ?
