Do not think that you can flee from Allah (swt) by your self – sufficient. For as long as your aggression lasts, you must return to Him (swt).
In this verse Allah (swt) brings the preposition and its related noun (to your Lord) at first to restrict the statement. Meaning that the return is exclusively to Him (swt) and not to any other than Him. The beginning is from Him (swt) and the return is to Him (swt), no escape.
الرُّجْعَى (Return): it requires leaving either to Paradise or to Hell. Note, there is no good in goodness after it would be a fire, and there is no evil in evil after it would be heaven.
