1 Timothy 4:10 and here is the motive of our toiling and wrestling, because we have our hopes fixed on the ever-living God, who is the Saviour of all mankind, and especially of believers. (WEY)
1 Chronicles 28:9 You, Solomon my son, know the God of your father, and serve him with a perfect heart and with a willing mind; for Yahweh searches all hearts, and understands all the imaginations of the thoughts: if you seek him, he will be found by you; but if you forsake him, he will cast you off forever. (See NIV)
