A look at the word 'Fullness', shows it is translated abundance. It is actually God's desire to give us life in abundance, in fact, more abundantly (John 10:10 NKJV). This means everything: life, health, happiness, prosperity - you name it. God's wish is to bless us as we walk in obedience to His Word.
The thing is, we need to trust Him; we need to believe that He wants the very best for us. This is where our faith Comes in. We see in 2 Corinthians 5:7, that we walk by faith, not by sight. This means we have to trust that, no matter what, He will meet our need from His riches in Glory (Philippians 4:19). We may not see it now, but as we look through the eyes of faith it becomes a reality. Our job is to reach out and take it by faith - to receive it.
However, if we want God to be a giver to us, we must be a giver to Him. This is where tithing comes in. Charles F Stanley writes, 'God has set forth very specific directives about what He expects us to give back to Him. Malachi 3:8-12 clearly teaches us that we are to give Him a tithe, which is 10% of what we produce or earn. ' The word 'tithe', is based on the number ten in Hebrew.
Sometimes believers fail to give what God calls them to because they feel they will not have enough to live on. The thing is, we cannot outgive God. Be confident that He will give to you and meet your need because you're following Him in obedience.
God longs for us to walk in faith with Him. Jesus explained it clearer in Mark 11:22-24 (read it for full understanding). Whenever we ask God for something in prayer, we are to believe that we receive them and we will have them. Oral Roberts used to say, 'Doubt and do without, with faith, believe and receive - expect a miracle.'
Notice those last three words - Expect a miracle. We pour doubt on things too much. We ask God for something and then cancel it out with doubt by confessing, 'I still feel unwell,' or 'We'll never get through this financial crisis.' Stop the 'I can't' and replace it with, 'I can, with God's help.'
Why not believe for a miracle today? Believe and receive; in other words ,'Take it'.
