“And you will seek Me and find Me, when you search for Me with all your heart.”Jeremiah 29:13 NKJV
The key to following Jesus Christ is doing so with our whole heart. God has not called us to simply give Him lip service. There are those who praise God with their lips but their hearts are far from Him.
The Lord sees all things. There is nothing hidden from Him. If there are areas in our lives the Holy Spirit is speaking to us about and convicting us then we need to be obedient and turn from those things.
To pursue the Lord with our whole heart simply means to make Him the number one priority. He will strengthen us for all things and give us wisdom. But we must pursue Him with our whole heart. When we pursue Him with our whole heart we will experience the abundant life Jesus talked about.
