For example, if someone was saved at a very young age but lived a life full of sins their whole adult life, yet asked for forgiveness along the way, is there a point where God would stop forgiving?
1 John 1:5 - 10
ESV - 5 This is the message we have heard from him and proclaim to you, that God is light, and in him is no darkness at all. 6 If we say we have fellowship with him while we walk in darkness, we lie and do not practice the truth.

When we accepted Jesus payment for all our sin, He gave us His perfect righteousness. Romans 4:5 So we are counted righteous before God when we received the free gift of God, and our sins can no longer be imputed to our account. Romans 4:1-8
But First John 1:8 says we all still sin which gives grace the occasion to work. Grace is the well that never runs dry. It is the living water. But we all reap what we sow.
Our works have nothing to do with salvation which is a free gift, but they do have to do with our rewards in heaven. Those that overcome sin and live according to the spirit will lay up treasures in heaven.
Our works will be tested by fire. But our spirit will be saved because of Jesus blood sacrifice for all sin. If we stay in sin and do not repent, we may lose our rewards in heaven, and maybe our life, but not our salvation which was complete in Him when we first believed. First Corinthians 5:5
But our works have nothing to do with salvation, which is a free gift when we accepted it by faith alone. We all sin and come short of the glory of God. But where sin abounds, grace much more abounds. If It were not for the grace and mercy of God, no one would be saved. Titus 3:5.
But we are His workmanship created in Christ Jesus to do what He has called us to do. We are in Him and He in us.
But any one who preaches a gospel that says we are saved by our works, is preaching another gospel and will be accursed. Galatians 1:8-9
Ephesians 1:13 We have been sealed by the Holy Spirit when we first believed so our salvation is complete in Him who saved us by grace. We can not work our way to heaven.
But after we have received grace for salvation we do good works to lay up treasure in heaven. Good works can not save us, but will have a reward in heaven that will last through out eternity. Gods grace Is sufficient for all our sin. If it was not, no one could be saved.
