Such a Christian is a person who, for whatever reasons, is focussing on the worldly aspect of life rather than spiritual ones. I find myself in this situation more than I care to admit to and certainly more than I like. When I identify this behaviour I pray for forgiveness and for the strength and courage to allow God to run my life, to "Let Go and Let God", as the adage goes.
I agree with the things that sbuthpstr stated, and am also grateful for a God who is endlessly loving, patient and forgiving. I pray daily for the strength and courage to let God into my life completely and to deny Satan his way with me. For me it is a constant struggle and I pray God will equip me to prevail.
I look forward to this Bible Study, the interaction with other students and to improving my ability to live in Christ, and with God, through the things I will learn.
God's Blessings to you all,
George
