Heart worship is the only worship that is acceptable to God
Isaiah 29 v 13, 14
God willing people will be able to gather together to worship God from next Sunday. Only those whose heart has been made right with God on faith in Christ Jesus can truly worship God. The sinner without Christ as Saviour is at enmity with God so they cannot properly worship God. The believer can worship God but it's only worship offered in Christ that results in the sin attached to our worship being forgiven and therefore made acceptable to a Holy God.
We are displeasing God as believers if we don't gather with other believers to worship God as He requires. However, Isaiah points out that it wasn't that the people neglected to worship God but didn't do it from the heart. There is nothing more common and dangerous as a mere formal outward worship of God. It is not acceptable to God to be in church singing His praises, praying and hearing God's word if it's not done sincerely from the heart. All of these things are worth nothing if not coming from the heart for that is what God looks upon.
It is heart praise and prayers that are pleasing and acceptable to God. Also it is responding to the preaching of God's word in the heart with faith and obedience that's pleasing and acceptable to God. So don't fall into the trap of bringing your body to church to worship God while your heart is somewhere else!
"Yet I may love Thee, too, O Lord,
Almighty as Thou art,
For Thou hast stooped to ask of me
The love of my poor heart."
