You can handle it

The phrase "God will never give you more than you can handle" is a misinterpretation of 1 Corinthians 10:13 in the Bible. The verse actually says, "God is faithful, and he will not let you be tempted beyond what you are able". It also says that God will provide a way out so that you can endure the temptation. 
The verse is about temptation, and what God promises when we face it. It doesn't mean that God will never give us more than we can handle, but rather that there will always be situations that we won't be able to handle on our own. 
Here are some other things to consider about the verse:
• The Greek word for "temptation" can also be translated as "testing" or "trial". 
• The verse is a promise that God will be with you to walk through any difficulty. 
• The verse is a reminder that we should look beyond ourselves to the pain and suffering that others endure. 
• The verse can help us learn to become more dependent on God. 

Lean not on your own understanding” is a phrase from the Bible, Proverbs 3:5, which instructs people to trust in the Lord and not their own knowledge: 
• Trust in the Lord: Put all your trust in the Lord, including your will, intellect, and emotions. 
• Don't lean on your own understanding: Don't rely on your own strength and knowledge. 
• Acknowledge the Lord: Acknowledge the Lord in all your ways, and he will direct your paths.
