Psalm 100:4 Enter into his gates with thanksgiving, and into his courts with praise: be thankful unto him, and bless his name.
We can, we may, and we should enter into the Presence of God (His gates, His courts) with thanksgiving, praise, and blessing. Whenever and wherever we are, His Presence is with us, for God is with us always. We may consciously and purposely enter because of the blood of Jesus and His name (Immanuel, God with us). Wherever we go, He goes with us, and we with Him. Our body is a temple of God, where He resides constantly. Entering is recognizing that truth and remembering that promise. We enter every morning and throughout the day, and we go into the public assembly of the saints weekly.
When we are conscious of God with us we are naturally thankful for what He does and full of praise for who He is. And we bless His name, that is, we say good about God and to Him. The Lord initiates this response by loving us, sending His Son, forgiving, saving, and giving His Spirit to indwell. We enter in daily by giving thanks, praise and blessing.
