Galatians 6:7-8 is only an observation. It's quite simply saying that believers sow to the Spirit and unbelievers sow to the flash. So both Saints and Reprobates reap their just reward.Galatians 6:7-8
Do not be deceived, God is not mocked; for whatever a person sows, this he will also reap. For the one who sows to
his own flesh will reap destruction from the flesh, but the one who sows to the Spirit will reap eternal life from the Spirit.
Your opinion is not based on the text states.
Your opinion is a philosophical idea that a believer is eternally secure regardless of how they behave.
Gods people reap the reward which the Lord Jesus purchased for us at the cross. The reprobate reap the reward of eternal punishment in hell, because that exactly what they deserve.
How many times does God forgive one of His elect? you make it sound like He'ss just waiting for us to step out of line so He can condemn us. But Gods Word reveals there is no limit to Gods mercy towards His people, and there is no sin that can separate us from Him.
The Apostle Peter was a sinner, who was angry with his brother and he wanted to punish him for his transgression againt him. So he asked the Lord Jesus for His advice.
Matthew 18:21 Then Peter came to Him and said, "Lord, how often shall my brother sin against me, and I forgive him? Up to seven times?"
22 Jesus said to him, "I do not say to you, up to seven times, but up to seventy times seven."
If a sinner is commanded to forgive his brother 490 times, then an infinitely merciful loving God would forgive every sin His children committed against Him.

The Lord Jesus has already paid for all of our past, present and future sins. So those warnings are not for us, they are for the fake christians.
