Today

"For he is our God, and we are the people of his pasture, and the sheep of his hand. Today, if you hear his voice, do not harden your hearts, as at Meribah, as on the day at Massah in the wilderness,," Psalm 95:7-8

At these historical places Israel had acted shamelessly against the Lord (cf. Exod 17:1–7; Num 20:1–13). Despite God saving Israel, they questioned and tested the Lord, much like you and I do. Verses 1 and 2 call us to remember his works of salvation in our lives and to let our praise and gratitude to flow out of that. When I'm grateful, I might ask for more, but I'm recognizing what has already been given and contentment flows out of that. 

Psalm 95 speaks volumes about how great our redeemer is, but also about what He has done. he has been patient and long suffering. This is because real love is persistent and God loves His children. We also are called to be long suffering with the idle, timid, and weak. That means we are to warn, encourage, and help one another for a really, really long time! Change does not happen in us or others overnight. 

God knows our past mistakes. He knows how we have failed Him before, but there is so much grace in that word "Today" in verse 7. If he calls on you to do something today, do it and know that your heavenly Father loves you and is for you. Move forward, past fear, into obedience.
