There's no point focussing on "what if"s of the past; God is faithful, when we trust Him with our mistakes, they are no longer our burdens to carry, no longer ours to keep visiting, mulling over & owning. Why not spend that time meditating on the "what if"s of the future, now that's a lot more fun !
If you could do ANYTHING with your life, what would it be ?? ;)
