I don’t believe in the phrase “Once faithful, always faithful”. In my opinion this is basically saying that you can’t ever mess up. On the contrary, life is full of temptations that are coming your way like bullets. No matter what type of safe haven you’re in you’ll face them sooner or later. They are there to test you. It is up to you to decide whether to give into them or stay faithful and obedient.
“For a righteous man may fall seven times and rise again, but the wicked shall fall by calamity.” -Proverbs 24: 16
Sometimes you are going to fall. Sometimes you’re going to make the wrong choices. Trust me I know plenty of Bible characters who messed up at least once. Abraham had a child with his maidservant, trying to help God with the promise He made to him that he would have a son. King David committed adultery with Bathsheba, and had her husband. murdered. The prophet Elijah had a moment of doubt and ran for his life from Queen Jezebel. And you can’t forget about Peter who acted like a fake friend by denying Christ three times. But they also had one thing in common, they repented.
Despite how hard you may fall, how many times you falter, the best thing to do is get back up and seek to do better. When we fall, the best thing to do is recognize what we did, and ask God for forgiveness, and move on.
There is no need to beat yourself up as a reminder for what you did. If you do this how are you supposed to move on. More than likely you’re going to be miserable and depressed. God will forgive you. You just have to be able to forgive yourself. I know- it’s easier said than done.
Also, don’t try to overcome by your own will power alone, because let’s be honest those temptations and addictions you face can outweigh you. My best suggestion is to call on God for strength. I will be the first time admit that I know when I am in over my head and need a little help.
God bless, and have a wonderful day.
