In the Bible, only One fulfilled all that God had purposed for Him, and that's Christ. Everyone else missed something of what God had for them. Abraham produced an Ishmael, Moses did not enter the Promised Land, and even David confessed that his house was not fully in order at his death. While we may never be perfect, nonetheless, we're cautioned that we must not self-sabotage the call of God in our lives. Elijah's experience speaks into this subject vividly.
