"Faithful is He who calls you, and He also will bring it to pass."
1 Thessalonians 5:24
God is faithful and He will complete what He has started in those He has called. He starts with wooing us and melting our hearts to receive Him. But it doesn't stop there. He continues to grow us and mold us into the image of His Son. We have no righteousness of our own, only that which is imparted to us through Christ. "We need no more to make us happy, than to know the grace of our Lord Jesus Christ. He is an ever-flowing and an over-flowing fountain of grace to supply all our wants." (Matthew Henry)
