But He said to me, My grace (My favor and loving-kindness and mercy) is enough for you [sufficient against any danger and enables you to bear the trouble manfully]; for My strength and power are made perfect (fulfilled and completed) and show themselves most effective in [your] weakness. Therefore, I will all the more gladly glory in my weaknesses and infirmities, that the strength and power of Christ (the Messiah) may rest (yes, may pitch a tent over and dwell) upon me!
(2 Corinthians 12:9-10 Amplified Bible)

Pride¬†is the worst enemy a Christian can have inside of them. It will completely stop the presence and power of God in your life. Pride says I do not need help and I can do it all by myself and I do not need to bother God. God Almighty will not do anything or interfere in your life against your will! Proverbs 16:18 say, “Pride goes before destruction, And a haughty spirit before a fall.” Walking in fellowship with God means to share your very life and very existence with Him. The Lord Jesus Christ told the Apostle Paul in 2 Corinthians 12:9-10, “And He said to me, ‘My grace is sufficient for you, for My strength is made perfect in weakness.’ Therefore most gladly I will rather boast in my infirmities, that the power of Christ may rest upon me.”

When you realize the Lord Jesus Christ is your only strength and you are weak in your self before the trials and adversities in life. Then at the place Christ is strong in and around you. When you yield yourself to Him and realize that His strength and power can only work through you when you humble yourself and yield yourself to Him. Then His strength will live and flow through and around you.

For whatever is born of God overcomes the world. And this is the victory that has overcome the world; our faith. Who is he who overcomes the world, but he who believes that Jesus is the Son of God?
(1 John 5:4-5)
The righteous cry out, and the LORD hears, And delivers them out of all their troubles.
(Psalm 34:17)
I will cry out to God Most High, To God who performs all things for me.
(Psalm 57:2)
Then they cry out to the LORD in their trouble, And He brings them out of their distresses.
(Psalm 107:28)
And what is the exceeding greatness of His power toward us who believe, according to the working of His mighty power which He worked in Christ when He raised Him from the dead and seated Him at His right hand in the heavenly places, far above all principality and power and might and dominion, and every name that is named, not only in this age but also in that which is to come. And He put all things under His feet, and gave Him to be head over all things to the church, which is His body, the fullness of Him who fills all in all.
(Eph 1:19-23)
