The Bible is very comfortable with the idea that you can talk to God. Depending on the Bible version you look at ‘prayer’ is referenced over six hundred and fifty times!
What part do we play in faith? How does that relate to the promises of God? All through the Bible it seems a person has a great deal to do – for example David didn’t wait for God to slay Goliath?
Living in faith means to live trusting in the one you have placed your faith. Christians live by faith in God through Jesus Christ as enabled by the Holy Spirit.
In that sense ‘faith’ is the basic requirement of the person of God. It is not that faith saves (Jesus does that), but that faith is the way the saved person lives.
What does that have to do with the promises of God?
