The LORD is my strength and my shield; my heart trusts in Him, and I am helped. Therefore, my heart leaps for joy and I will give thanks to Him in song. Ps 28:7 NIV - with an assist from NASBA quick google on "strength" and you discover there are some really stupid ways people look for strength. The internet is filled with inane quotes on strength - I may be guilty of having repeated a few of them a time or two. ::grin::
While this verse doesn't tell me everything about strength or joy - it gives me a strong start. To truly experience God, I will walk through some "things" and this is ultimately good.
If it flees when life gets hard, it's not the joy of the LORD.
I won't know Him as my strength if I'm never given more than *I* can handle!
I won't know Him to be my shield if I never follow Him into battle.
I won't know Him to be my help if I never trust in Him and I won't trust in Him if I can handle everything just fine myself (see #1).
Because I HAVE experienced him as my strength, shield and help, my heart can and will leap for joy...even here....because the One who has proven Himself to be my strength, my shield and my trustworthy help does not change.
