Philippians 3:13-14 (KJV)
13 Brethren, I count not myself to have apprehended: but this one thing I do, forgetting those things which are behind, and reaching forth unto those things which are before,
14 I press toward the mark for the prize of the high calling of God in Christ Jesus.
Satan is the one who adds pressure on the Believer to discourage them from moving forward in life.
Paul said that we are to "press toward the mark..." meaning that we are going to face opposition in life. We will not get away from opposition, but we do not need to allow it to have authority over our lives. The word of God has the final say over every circumstance we face in life.
