Life is what it is. We do not ask to be born. We cannot request where we are to be born or to whom. Yet, here we are, as God decided. The best we can do is to "run with patience the race that is set before us”.
So, why should we be “looking unto Jesus” to author and finish "our faith"?
The Son of God, Jesus, became a human being just like us. He ran the race of life on this earth just like us. Jesus suffered and experienced some joy like all humans. He died and was the first human to be resurrected, never to die again. The Bible says Jesus will return and raise me and my family from death. That is my faith, and I am therefore depending on Jesus to finish what I am expecting in faith.
"For those God foreknew He also predestined to be conformed to the image of His Son, that He might be the firstborn among many brothers and sisters...Christ Jesus who died—MORE THAN THAT, who was raised to life—is at the right hand of God and is also interceding for us. Who shall separate us from the love of Christ?...I am convinced that neither death nor life, neither angels nor demons...nor anything else in all creation, will be able to separate us from the love of God that is in Christ Jesus our Lord.” (Romans 8:29-39)
I run my race as best I can, forgetting the blunders I make, and focus on my eternal destiny.
"Forget the past and look forward to what lies ahead...hold on to the progress we have already made...we are citizens of heaven, where the Lord Jesus Christ lives. And we are eagerly waiting for Him to return as our Savior. He will take our weak mortal bodies and change them into glorious bodies like His own..." (Philippians 3:13-21)
