If we accept Jesus Christ and we are born again of the Spirit of God then we have to be changed into the likeness of Jesus Christ. If we OBEY Jesus and we follow the guidance of the Holy Spirit He will change us into His likeness but we have to submit to the Holy Spirit. He will GUIDE us, He will TEACH us, He will FORM us and He will MAKE us, He will DISCIPLINE us and He He will SHAPE us so that we become LIKE Jesus Christ, so that we can be IN Christ and Christ can be IN US.
We have to change . we have to get into shape for the kingdom of Heaven and then we have to stay in shape, we have to go after Jesus and SUBMIT ourselves to Him, let Him have His way with us because if we turn away from Jesus and we become conformed to the world then we fit out of the kingdom of God, we become CASTAWAYS and we are not suitable for the kingdom of Heaven.
We have to stay in shape. we have to stay IN CHRIST to be able to enter into the kingdom of Heaven.
Have we been transformed into His likeness through our obedience to Him, through walking with Him day by day? Are we staying in shape because if we do not stay in shape we will not be suitable for His kingdom and He will say to us:" Go away I never knew you, you workers of wickedness."
Are we staying in shape? Are we staying with Jesus? Are we following the guidance of the Holy Spirit? Are we pleasing to our Master?
May Jesus bless you.
