Eph. 1:14 The Spirit is God's guarantee that he will give us everything he promised and that he has purchased us to be his own people. This is just one more reason for us to praise our glorious God.
God dwells in the heart of the believer by means of the Holy Spirit. When we become children of God we become dwelling places for the Spirit of God. When the Spirit is in us things begin to happen; we are changed. The work of the Spirit is to make that which is unholy holy before God. It is a process that never stops. He uses the Word of God to chisel away all that is unholy and has to go. He replaces the stuff that has to go with godliness. We slowly, but surely, take on the nature of our holy God. The active work of the Spirit in us is God's guarantee that we are indeed His children.
The Spirit is God's guarantee that the Word of God works for us. We are a people of the Word and God always stand by His Word. What God promises to do in us, for us, and through us He will do. We dare not question what God declares. Only those who dare to believe everything God declares are able to live holy lives.
We ought to be a people of much praise to our God for all He is doing on our behalf. We ought to never take it for granted or lose sight of it. God is doing amazing things in the lives of His children. To God be the glory forever and ever! We owe to our God all that we have become and will become in Christ. Let us always strive to be a people whom the Spirit can mold and shape into a people after God's own heart.
