God's good promises

“Not one of all the Lord’s good promises to the house of Israel failed; every one was fulfilled.” Joshua 21:45
God has made many promises throughout the Bible to His people. He promised the nation Israel to protect and provide for them in the wilderness and lead them to the Promised Land. And He kept His promise by sending the pillar of cloud and fire (which protected them from the pursuing Egyptian army at the Red Sea, and also led them through the wilderness), by providing manna and quail for them to eat, and water from the rock to drink. He led them into the Promised Land and gave them victory at the major cities – Jericho, Ai, etc. Canaan was a land of giants, yet God caused great fear to come upon them so they were defeated by the Israelites.
Consider also the promises given to us. God has promised to never leave us nor forsake us (Heb. 13:5, Matt. 28:20). He has promised that He will return and take us to be with Him in heaven (John 14:3). He has promised us the presence of the Holy Spirit (Eph. 1:13). He has promised to complete the work He has started in our lives (Phil. 1:6).
