Read Ephesians 2:1-3 (also Ephesians 3:14-19; Matthew 11:28-30)
I think sometimes we give ourselves a pass when it comes to our thought-life, our imagination, our inner being. The huge problem with this is that it is only in our thought-life or imagination that we hold genuine, saving faith in Jesus Christ. If your imagination is severed from Christ, so are you. Outer being follows inner being; walk comes from heart. So, your outer life may seem to look Christian, but that will change soon enough. It probably already has to a greater degree than you are aware of. If this is where you find yourself – away from Christ- then immediately shut down your will. Don’t “try” anything. Just discover what’s true. Ban anything in your conscience that smacks of a courtroom. Forget about guilt or innocence. Life and death are much more useful categories here. You want to get away from once again making a case for your good intentions. No one’s keeping score. You’re either dead or alive. Your only antidote is the Cross of Christ, where He who was alive became dead (and became sin per 2nd Corinthians 5:21), so that you who sin and are dead could become alive. Jesus is always your only chance, your last chance. Come to Him now – weary, burdened, and broken – and He alone will give you peace… and life. You can never give these to yourself.
