The first thing a Christian should know is that he is never rejected and never can be. He is hid with Christ in God (Colossians 3:3). No one can ever take a believer out of that place of total acceptance.
You can’t be a failure in the Finished Work. You can make a lot of mistakes and lose a lot of blessings, but a Finished Work Christian who has a wall of positional truth around him can never be labeled as a failure, though he may fail.
How can I feel rejected when God has accepted me forever in the Beloved (Ephesians 1:6)? How can I feel rejected when I have been forgiven through the blood of Jesus Christ to the praise of His glory? How can I feel rejected when I have been chosen in Christ before the foundation of the world (Ephesians 1:4)? How is it possible for me to feel rejected when the Father, the Son, and the Holy Spirit all dwell in me (John 14:23; 1 Corinthians 6:19; Romans 8:11)? I can’t feel rejected when I’ve got 7,834 Bible promises directed toward me.
God has all power, all love, all mercy, all forgiveness, all patience, and it’s all directed toward me.
