No, you're not, based on the merits of your life. You're good enough based on Jesus' merits, His sinless life. He did the work to get you eternal life and we know His sacrifice was acceptable because the Father raised Him from the dead to life. We are saved by grace through faith in Him. Does that mean your life doesn't matter? No, it means you are of infinite importance and your life has meaning and possibility every single day because of Him.
Abraham had more or less retired. Between Genesis 21 and Genesis 22 lies maybe 25 years or more of life with Sarah and Isaac and then God speaks and tells him to take his son and sacrifice him on a mountain God will tell him of. Abraham passes the test by faith, telling his son God will provide the ram for the sacrifice, and so God did. Abraham believed God because of his experience of God, walking before him all the days of his life. Choosing a life of faith doesn't mean there won't be tests, we are always challenged to have more faith, experience more of His goodness.
A life lived in faith is always pregnant with possibilities.
