This is the simple plea of God.
God loves you, no matter what you have done. I believe there is nothing you can do to invalidate that. The people of Israel had wandered off multiple times, and they had the promises, the miracles, the prophets all to remind them of the truth of God, His immediate presence and power. And yet they still rebelled, and required an Isaiah to call them back again. Still, God was merciful to them, still patiently called them to come back to him.
Now we, who have the resurrection of Christ as our proof, the providence of God as our constant witness, and the presence of the church as our reminder receive the same call as those ancient Israelites. Come back. We have wandered far from home. Come back. If if you have never known God, He knows you. Come back home.
God bless you today.
