God's grace is simply defined as God's favor. It is unmerited favor for all who believe on the Lord Jesus Christ. God's grace saves you as a believer from judgment and condemnation. More than that, God's favor is sufficient for you in all the situations of life.
If you are in a difficult situation, God has favor for you as a believer. A simple prayer receives God's favor, "God, Your grace is sufficient for me. Even in my difficulty, Your favor is sufficient in my weakness." Should God choose not to change your circumstances, He will give you grace to go through it. That's His favor for you.
A friend may ask another friend, "Will you do a favor for me?" You need not ask God such a question. His word in the Bible promises a favor sufficient. That's known as grace. You will find yourself in no situation where God's grace is not sufficient.
God can give you favor with people. He can give you favor in desperate circumstances. His grace knows no limits. God gives you His favor according to His purpose and for His glory. Pray that He will get glory out of all your circumstances. God's favor is for you.
"My grace is sufficient for you,
for My strength is made perfect in weakness."
2 Corinthians 12:9
