Victory over temptation and sin is not an achieving, but a receiving. The more we rely on Christ, look to Christ, the less we depend on ourselves. The living Christ is greater than any power of our own, or any power of the enemy. Only within this personal fellowship with God are we free from the fear of falling and sinning. If we fear we are going to fall, we are half way there.
Perfect love casts out fear.
Life with Christ is an assurance of victory. We are delivered from the futility of trying to live the Christian life without His help. The responsibility belongs to our Lord. Divine guidance becomes a new and vital thing to us. This awareness of Christ in our lives becomes a reality to us, constant and all-controlling.
