If you know that God loves you, you should never question a directive from Him.
Don't put labels on people. See them as people who Christ died for.
If you feel weak, limited, ordinary, you are the best material through which God can work.
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.
Our task is to relate our lives to God, and let Him work through us.
Wouldn't it be a tragedy to get to the top of the ladder and find you placed it against the wrong wall?
