We don't choose what we will do for God; He invites us to join Him where He wants to involve us.
Don't put labels on people. See them as people who Christ died for.
God speaks through a variety of means. In the present God primarily speaks by the Holy Spirit, through the Bible, prayer, circumstances, and the church.
We don't realise how much the world has affected us. We put God in the background.
Our task is to relate our lives to God, and let Him work through us.
Teach yourself to thankfully receive all that God gives you as evidence of His love and faithfulness, and then you'll find it easier to trust Him next time.
