God’s grace is entirely up to Him and there is no absolute guarantee to anyone that s/he will receive His grace. Ananias and Sapphira never had the opportunity to even regret or repent of their sins but died instantly for lying to Holy Spirit before the very man, Peter who denied the Son of God not just once but thrice. God’s grace on Peter isn’t same as to Ananias and Sapphira even though the sin of Peter is much greater than Ananias and Sapphira. Based on Scripture we can conclude that ,God gives grace to the humble, He is gracious to the one who lacks and the righteous will find grace in His sight.
