Is God's forgiveness somehow restricted, to only the believer?
No, Jesus Christ, the express image of God, Hebrews 1:3,
died for all men. However, why we need to believe we are forgiven, for as a man thinks in
his heart so is he, Proverbs 23:7.
Are we forgiven for all of our sins, even the one's we have not committed yet?
Yes, If we are not forgiven for future sins, all of us would lose our salvation,
For all have sinned, and come short of the glory of God;
Romans 3:23.
All means ALL but, the blood of Jesus Christ His Son
cleanses us from all sin,
1st John 1:7.
Jesus paid for our sins once and for all.
Unlike the other high priests, [Jesus] does not need to offer sacrifices day after
day. For Jesus does not need, as those high priests,
offered up sacrifice daily, first for his own sins and then for the people's sins. For
He did this once for all, when He offered up Himself,
Hebrews 7:27.
Once and for all, past, present and future sins.
All the followers of Christ, those before Christ (BC), and the people after Christ (AD)
have received salvation through Christ. There is not a date in time that grace does not
cover.
As long as we are living on this fallen earth, we are to a degree bound to sin.
All of us are bound to die, unless Jesus comes back first, death is directly caused by sin!
When desire has conceived, it gives birth to sin; and sin, when it
is full-grown, brings forth death, James 1:15.
If we say that we have no sin, we deceive ourselves, and the
truth is not in us, 1st John 1:8.
Does grace cover all my sins?
Yes, God is able to make all grace abound toward you,
2nd Corinthians 9:8.
All things are lawful for me, but all things are not helpful.
All things are lawful for me, but I will not be brought under the power of any,
1st Corinthians 6:12.
Where sin abounded, grace abounded much more, so that as sin
reigned in death, even so grace might reign through righteousness to eternal life through
Jesus Christ our Lord, Romans 5:20-21.
Shall we continue in sin that grace may abound? Certainly not!
How shall we who died to sin live any longer in it?,
Romans 6:1-2.
Our new (Spirit) man has died to sin, however, as long as our flesh remains alive,
we shall continue to have fleshly desires that are not always godly.
Can I fall from grace?
No, As long as you are living on this earth, You cannot fall from grace, The moment
when you die, (if you do not believe in Jesus Christ as your Lord and Savior), you have
then fallen from grace.
Grace without personal sanctification, (holiness) is actually a license to sin.
Do not cheapen the precious grace that God has purchased for us.
We then [apostle Paul], working together, we also call on you
not to receive the grace of God in vain,
2nd Corinthians 6:1.
Shall we sin because we are not under law but under grace?
Certainly not! Do you not know that to whom you present yourselves slaves to obey, you
are that one's slaves whom you obey, whether of sin leading to death, or of obedience
leading to righteousness? Romans 6:15-16.
If we are truly living for God, we shall walk in holiness better without trying to,
that if we concisely attempt to keep the letter of God's law.
