Come unto me, all ye that labour and are heavy laden, and I will give you rest.
Matthew 12:28 (KJV)
Jesus gives us rest because when we enter into Christ, we enter into a finished work. The moment we put our faith in Jesus as Lord of our lives, all things pertaining to life and godliness are made available to us. Our task is not to struggle and to work hard to try and get God to bless us, but to live each day open and receptive for the blessings we already have in Him to manifest in our lives.
Keep and guard your heart with all vigilance and above all that you guard, for out of it flow the springs of life.
Proverbs 4:23 (AMP)
Guarding the heart means we do not allow anything to rob us of the peace that has come to us as a result of our meditating on and believing the promises of Scripture. We determine to keep our hearts fixed on Jesus and on what His Word declares about us no matter what.
It is God that girdeth me with strength, and maketh my way perfect.
Psalm 18:32 (KJV)
God supplies us with strength and He leads us into His will for our lives as we trust Him and depend upon Him in all things. We limit God by trying to do things according to our own ways; yet when we trust in His leading and the guidance of the Holy Spirit, He will make our way perfect.
And I give unto them eternal life; and they shall never perish, neither shall any man pluck them out of my hand.
John 10:28 (KJV)
No one and nothing can ever separate us from the love of God. We have been joined unto Christ for eternity, and no amount of mistakes or shortcomings on our part can undo this union. Our role is to receive His precious gift of righteousness, and all that comes with it, by faith.
