We don't just feel or experience fear, but fear also has a language which isn't really helpful but fosters negativity in times of adversity. So we are bound to complain about the situation or difficulty at hand and likewise we shall remain in that position because we have already projected our negative self-defeating environment. As believers of Jesus Christ, we are are the sheep and He is The Shepherd. So, the Lord gives a command that when we adhere to, we receive overflowing blessings. As we seek to follow His instructions, His will becomes our command and since His will is perfect then we are perfected in Him. What a delight is is to have the right Posture....
Let us strive to fix our eyes on Jesus who is the leader and perfecter of our faith. (Heb 12:2)
