Here's where your theology falls apart.
You quoted those two verses. The first said if you don't love the Lord Jesus Christ then you are Anathema Maranatha.
The next verse say...if you love me, keep my commandments.
......Have you kept EVERY commandment of the Lord Jesus Christ? If not then by your own words YOU are "Anathema Maranatha".
Well, not all of God's Commands have dire consequences for a person's soul in the after-life if they were to disobey them (with no repentance). There are "
sins unto death" and there are "
sins that are not unto death" (1 John 5:16-18). "
Sins unto death" are sins that John mentions in Revelation 21:8. They are murder, sexual immorality, lying, and idolatry, etc. They are called "
sins that lead unto death" because they lead to the "
Second Death" (i.e. the Lake of Fire). "
Sins not unto death" would be hidden or secret faults (Psalms 19:12), not being baptized in this life (1 Peter 3:21), and or boasting in each other (whereby divisions can be caused) (1 Corinthians 3:1-15).
Therefore, when Jesus is talking about if you love me, keep my commandments, He is saying that you will naturally keep those commands that deal with the salvation of your soul because it would mean you truly want to be with Him for all eternity by keeping His good ways that speaks of His good character. For God is good; And God is love. If we are of God's Kingdom, we would want to be loving and good like Him (conformed to His likeness).
But saying words like, "all my future sin is forgiven" or "we are not saved by anything we do" just encourages people to treat sin as if it was no big deal. However, Scripture tells us it is a big deal because committing sin or certain sins are tied to having dire consequences to our soul in the after-life (See Matthew 5:28-30, Matthew 6:15, Matthew 7:23, Matthew 12:36-37, Matthew 13:41-42, John 12:48, 1 John 3:15, Revelation 21:8).
