What the Holy Bible says about Uncertainty:
105 Your word is a lamp for my feet, a light on my path. (Psalm 119: 105)
23 They are new every morning; great is your faithfulness. (Lamentations 3:23)
26 In the same way, the Spirit helps us in our weakness. We do not know what we ought to pray for, but the Spirit himself intercedes for us through wordless groans. (Romans 8: 26)
12 I know what it is to be in need, and I know what it is to have plenty. I have learned the secret of being content in any and every situation, whether well fed or hungry, whether living in plenty or in want. 13 I can do all this through him who gives me strength. (Philippians 4: 12-13)
17 And whatever you do, whether in word or deed, do it all in the name of the Lord Jesus, giving thanks to God the Father through him. (Colossians 3: 17)
